  • Software for the verification of Timoshenko beam finite elements
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): David Day The classic paper Han et al. Dynamics of transversely vibrating beams using four engineering theories, Journal of Sound and Vibration, 225, 1999, sets up the continuation problem that determines the exact vibrational frequencies and mode shapes of prismatic Timoshenko beams. This article presents a portable implementation of a solver for the problem.In order to reliably compute a complete set of modes, without redundancies, it is crucial to formulate the frequency equation as a continuation problem. The continuation problem is solved for a thickness parameter starting from zero thickness (the Euler beam), and increasing up to the finite thickness of interest. The continuation problem has a bifurcation point, at which a wave number variable passes from real to a purely imaginary value. For finite thickness, the continuation problem for all sufficiently high frequency modes crosses through this bifurcation. Han et al.[7] solve the continuation problem using an unspecified differential equation solver, and dummyTXdummy- do not discuss accuracy. Here a solution of the continuation problem using pseudoarclength continuation is presented. This article presents a description of how to compute this singularity exactly, and develops software that maintains full working precision. Furthermore the details of the computation of the mode shapes from the frequencies are presented for free-free, clamped-clamped and clamped-free boundary conditions. The source code is available under a MIT license from github in the TimoshenkoBeamEigenvalues repository.
       
  • A view-based 3D CAD model reuse framework enabling product lifecycle reuse
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Chao Zhang, Guanghui Zhou 3D CAD models have great significances for product lifecycle reuse as each model aggregates abundant knowledge in a vivid 3D CAD model and enables engineers to reuse the existing mature designs from a high-level perspective. The effective reuse of the pre-existing 3D CAD models could greatly save time and cost in new product development. Consequently, this paper proposes a novel view-based 3D CAD model reuse framework, which supports the effective reuse of 3D CAD models throughout the new product lifecycle by a deep learning approach. In this framework, each 3D CAD model is first represented by a series of orthogonal two-dimensional views, which contain rich spatial information for differentiating 3D CAD models. Then, we define the problem of model retrieval as a view recognition problem, where a deep residual network (ResNet) is successfully trained to facilitate the view-based 3D CAD model retrieval. With the learned ResNet, engineers could take the understandable views of a model that represent their query intents as input and acquire the relevant 3D CAD models for product lifecycle reuse. Finally, the typical application scenario demonstrates the feasibility of the proposed framework, and the evaluation experiments show the superiorities of ResNet used in this framework.
       
  • Relating structural test and FEA data with STEP AP209
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): R. Lanza, J. Haenisch, K. Bengtsson, T. Rølvåg This paper proposes a method for incorporating FEA data and structural test data into one common standardized data model based on the ISO 10303 STEP Standard [1]. The proposed method takes advantage of data structures and elements defined in STEP AP209 Edition 2 [2] to provide traceability between analysis and testing phases; information such as sensor and finite elements, test and FEA load cases, and test and FEA results are included. It also presents an introduction to STEP and AP209e2, and discusses how it can be used in a Simulation Data Management environment.
       
  • Tools and techniques for building models for isogeometric analysis
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Anna Perduta, Roman Putanowicz Isogeometric Analysis (IGA) is a new computer method that has gained much attention in recent years. Its distinguishing feature is the use of parametric representation of curves, surfaces and solids, based on Non-Uniform Rational B-Splines, which are also used as shape functions in Galerkin approximation schemes. NURBS are commonly used in CAD modelling packages, thus among other advantages IGA facilitates use of CAD models as geometric domains for solving Boundary Value Problems. IGA is a relatively young method and despite its popularity there still is a small number of tools available, especially in comparison with Finite Element Method. This is notably nagging issue in case of tools for preparing geometric models for IGA. In this paper we discuss several popular tools and tricks that can be used in place of dedicated IGA preprocessor. The presented techniques can be particularly useful for researchers interested in starting work in IGA field, as they can speed up generation of comprehensive models and are incentive for data sharing, an important point from research reproducibility perspective.
       
  • Prediction of dynamic properties of ultra-high performance concrete by an
           artificial intelligence approach
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Mohammad Reza Khosravani, Sara Nasiri, Denis Anders, Kerstin Weinberg Significant advances in new generation of concrete led to construction of ultra-high performance concrete (UHPC). Since the demands of this engineering cementitious material have been increased, investigation on mechanical behaviour of this material is an interesting topic in today’s research programs. Over the years, strain-rate sensitive behavior of UHPC material has been studied by experimental tests. In the current research, an artificial intelligence (AI) system is implemented which can predict dynamic mechanical properties of UHPCs constructed by various mixtures. This system is able to predict elastic modulus, compressive strength and tensile strength, all under high rate of loading. The system is developed within the framework of case-based reasoning (CBR) methodology as a problem-solving AI method. CBR is a learning methodology which utilizes similar previous cases to solve particular new problems. In this paper, case-base of the implemented system is enriched by a literature study of numerous researches which tested various UHPCs. The proposed intelligent system has been applied to reduce human expert dependency and avoid time consuming experimental tests. The implemented system is evaluated by available results from experiments under high rate of loading.

    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Arturo Delgado-Gutiérrez, Diego Cárdenas, Oliver Probst This paper presents an efficient and automated algorithm for the generation of straight and curved blades, as used in horizontal- and vertical-axis wind turbines. A single B-spline surface with both structural and aerodynamic zones is constructed, based on Non-Uniform B-splines Functions. The overall process of the approximation of both 2D blade airfoils and 3D blade surfaces is presented. The main algorithm is designed to construct a detailed B-spline surface, minimizing the segmentation data of the blade and the number of control points needed. A comparison between uniform and non-uniform B-splines blades is conducted using strain energy analysis. Additionally, the Double Reflection Method is implemented as a Rotation Minimizing Frame for a robust transformation of a 3D straight blade into a curved blade, following an arbitrary 3D pole curve. The final output of the main algorithm is a low-resolution control mesh that can regenerate a high-resolution 3D curved NURBS blade. The novel method is designed as a pre-step for numerical analysis, such as classical Finite Element Method and Isogeometric Analysis.
       
  • Push-pull direct modeling of solid CAD models
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Qiang Zou, Hsi-Yung Feng Direct modeling is a very recent CAD modeling paradigm featuring direct, intuitive push-pull interactions with the geometry of the model to much increase model editing flexibility. The major issue for push-pull direct modeling is the possible inconsistency between the altered geometry of the model and its unchanged topology. The challenge of resolving the geometry-topology inconsistency lies in ensuring that the resulting model remains as a valid solid model and that the model shape follows a continuous change pattern. Although push-pull direct modeling has been implemented in several CAD software packages, robustness towards generating valid modeling results and continuous shape changes still remains an open issue. This paper proposes a systematic method to handle the resolution of any possible inconsistent situation. The method formulates the continuous shape change requirement as successive Boolean operations on the model volume, thereby guaranteeing valid solid models and continuous shape changes. Further, this formulation allows an easy implementation of push-pull direct modeling using existing CAD research and engineering results. In order to show the effectiveness of the proposed method, a software prototype is developed and the modeling results are compared with those of five leading CAD software packages.
       
  • A simplified method to predict fatigue damage of TTR subjected to
           short-term VIV using artificial neural network
    • Abstract: Publication date: December 2018Source: Advances in Engineering Software, Volume 126Author(s): Eileen Wee Chin Wong, Do Kyun Kim Marine riser is the critical component transporting hydrocarbon and fluid from well to the platform and vice versa. Riser experiences vortex-induced vibration (VIV) caused by current, leading to fatigue damage. Estimation of VIV fatigue damage is essential in designing feasible and operable riser. A simplified approach for predicting fatigue damage is required to reduce the computation time to analyse the fatigue damage. This study aims to propose a simplified approach to predict VIV fatigue damage of top tensioned riser (TTR) using artificial neural network (ANN). A total of 21,532 riser model was generated with different combination of six main input parameters: riser outer diameter, wall thickness, top tension, water depth, surface and bottom current velocity. The modal analysis was performed using OrcaFlex and VIV fatigue damage of the riser was computed using SHEAR7. The six input parameters and corresponding fatigue damage results made up the database for training a 2-layer neural network. Weight and bias values acquired from the training of ANN were used to develop the VIV fatigue damage prediction model of the riser. The hyperparameters of the ANN model were tuned to optimize performance of the model. The results showed the final ANN model predict fatigue damage well with shorter time compared to conventional semi-empirical method. Hence, the proposed approach is suitable to be used for prediction of VIV fatigue damage of TTR at early design stage of TTR.Graphical abstractImage, graphical abstract
       
  • A Schur-complement model-order-reduction technique for the finite element
           solution of transient elastohydrodynamic lubrication problems
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): W. Habchi The current work presents a reduced order finite element modeling framework for the solution of transient elastohydrodynamic lubrication (EHL) problems. The model order reduction technique is based on a Schur-complement method, applied to the elastic part within EHL problems. As such, it is exact and introduces no additional errors to the solution, with respect to the standard non-reduced finite element model. The technique reduces by one, the dimension of the linear elasticity part within the EHL problem. The use of the Schur-complement method however leads to a semi-dense Jacobian matrix. This is why the technique is complemented with a splitting procedure, allowing it to retrieve a standard finite-element-like sparsity pattern. In terms of computational performance, it is shown through a set of numerical experiments that the proposed reduced model offers a speed-up in computational times of the order of 15:1, compared to the equivalent full model, without any compromise on the accuracy of the solution.
       
  • Numerical simulation on fracture resistance and factors affecting
           toughness for welded joint of low-alloy steel
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Longfei Zhao, Xiangyu Guo, Haichao Cui, Fenggui Lu Crack propagation resistance for welded joint was numerically simulated by ABAQUS software, where compact tensile (CT) specimens with different thickness and depth of side groove were taken to discuss the variation and reliability of results. It is found that the critical fracture toughness Jc increases with the thickness and then decreases gradually to the plane strain fracture toughness. The equivalent thickness Beq was put forward by numerical simulation. Strain energy density and the volume of plastic deformation zone were calculated to explain the effect of thickness on Jc based on the theory of energy dissipation. The simulated results revealed that another critical geometry factor like the depth of side groove up to 25% of total thickness contributed to a smaller J integral distribution gradient. The CT specimen with suitable geometry size was obtained according to the numerical results, which helps in guiding the experimental test of fracture toughness. The simulation results of fracture resistance demonstrate a good consistency with experiments, showing that numerical model is of high reliability, and stable Jc could be achieved at suitable specimen size.Graphical abstractImage, graphical abstract
       
  • A method for analyzing stability of tower-line system under strong winds
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Bo He, Mingxi Zhao, Wentao Feng, Yaping Xiu, Yu Wang, Lijun Feng, Yongjian Qin, Chukun Wang Typhoon is a kind of bad weather affecting the safety of overhead transmission lines seriously. In recent years, mechanical failures, such as tower collapse and strand breakage from strong winds, have frequently occurred in coastal typhoon-prone areas in China. From the view of mechanics, the transmission lines should be considered as a tower-line coupling system entirety and dynamic loads should be taken into account. However, existing design specifications are insufficient for the consideration of dynamic loads. To analyze the stability of the tower-line system, the wind-induced response of the system was evaluated-with the tower-line coupling considered-by finite element modeling, and an effective method was introduced. Firstly, a finite element model containing three towers and two line segments was set up in accordance with actual transmission lines having a disaster history of strong wind. Secondly, static and dynamic wind loads were applied to the model, and the stress distribution was simulated. Thirdly, the relationship among the largest stress value, wind speed and wind direction was established, and the stability limit of the transmission line was evaluated. The method showed good efficiency in evaluating the mechanical properties of the tower-line coupling system under strong wind conditions, and the results are consistent with accident records.
       
  • A novel principal components analysis (PCA) method for energy absorbing
           structural design enhanced by data mining
    • Abstract: Publication date: January 2019Source: Advances in Engineering Software, Volume 127Author(s): Xianping Du, Feng Zhu A PCA based structural design methodology is proposed and applied to the vehicle structure crashworthiness design. The aim of this approach is to develop structures with complex geometry to satisfy the energy absorbing design requirements using reduced number of design variables. This method is assisted by data mining technique to discover the implicit interrelationship of these variables and generate corresponding design rules. In this approach, the surface of structure is described by the control points, in the form of non-uniform rational basis spline (NURBS). The large control point dataset is compressed using PCA technique, which is able to reduce high-dimensional data by expressing them with a set of linearly uncorrelated orthogonal basis, i.e. Principal Components (PCs), together with corresponding Principal Components Scores (PCSs). By changing the value of the PCSs, the geometry of the part can be modified. Through this process, instead of directly handling a huge number of geometry control points, one can perform the design by adjusting the values of a small number of PCSs, and thus the computational cost is significantly reduced. As a case study, the vehicle frontal side rail (known as an S-shaped beam) is designed using this method. After the design is complete, a data mining process is performed, to explore the implicit interrelationship between design variables (i.e. PCSs), and generate design rules to guide the design procedure. The results suggest that the PCA approach can be used to design a complicated structure with irregular shape effectively and efficiently, and overcome the weakness of conventional design methods, i.e. limited capability of handling high-dimensional design variables and big design datasets. The subsequent data mining process enhances the design procedure by revealing some critical interrelations between parameters and generating design rules for practical applications.
       
  • An accurate meshless formulation for the simulation of linear and fully
           nonlinear advection diffusion reaction problems
    • Abstract: Publication date: Available online 22 October 2018Source: Advances in Engineering SoftwareAuthor(s): Ji Lin, S.Y. Reutskiy In this paper, a new meshless semi-analytical collocation technique is presented for the simulation of time-dependent linear and fully nonlinear advection diffusion reaction equations (ADREs). The time-dependent nonlinear problem is reduced to the system of linear problems in each time layer by using the quasilinearization technique in combination with the Crank–Nicolson scheme for the temporal approximation. Then it may be solved by the meshless backward substitution method. In the backward substitution method the approximation is given to satisfy the boundary conditions as a prior. Then the approximation is substituted back to the governing equations where the unknown weighted parameters are obtained using the collocation approach. The developed method has been tested on seven concrete problems for a range of free parameters. The comparison of the obtained numerical results with those available in literatures reveals that the proposed method can accurately approximate linear and nonlinear advection diffusion reaction problems. This method can also be easily extended onto other linear and nonlinear transient problems in 1D, 2D, and 3D due to its general idea and easy implementation.
       
  • An advanced CAD/CAE integration method for the generative design of face
           gears
    • Abstract: Publication date: December 2018Source: Advances in Engineering Software, Volume 126Author(s): Yuanhang Wu, Yuansheng Zhou, Zhenyu Zhou, Jinyuan Tang, Hongwu Ouyang The conventional generative design of face gears involves CAD modeling and stress analysis by finite element analysis (FEA), which is usually performed repeatedly by optimizing design parameters until acceptable stress result is obtained. An integration of computer-aided design (CAD) and computer-aided engineering (CAE) can significantly reduce both time and labor costs to this generative design. However, this idea has not been adopted by any commercial software in designing face gears due to the complicated tooth surface geometry. The main problem is that the isoparametric discretization points of the tooth surface are non-equidistant. In this work, we derive an advanced method, based on the geometry characteristic of the tooth surface, to calculate the points as an even distribution on the tooth surface. In this method, sample points are discretized according to gear blank geometry and then a mapping between sample point and tooth surface point is established; according to which a comprehensive algorithm is proposed to recalculate the tooth surface points. Subsequently, the calculated tooth surface model is input to the proposed CAD/CAE integration method to implement the finite element analysis (FEA). The proposed method is validated by a series of face gear drives with varying shaft angles.
       
  • OpenMP and MPI implementations of an elasto-viscoplastic fast Fourier
           transform-based micromechanical solver for fast crystal plasticity
           modeling
    • Abstract: Publication date: December 2018Source: Advances in Engineering Software, Volume 126Author(s): Adnan Eghtesad, Timothy J. Barrett, Kai Germaschewski, Ricardo A. Lebensohn, Rodney J. McCabe, Marko Knezevic We explore several parallel implementations of an elasto-viscoplastic fast Fourier transform (EVPFFT) model using Message Passing Interface (MPI), OpenMP, and a hybrid of MPI and OpenMP to efficiently predict micromechanical response of polycrystals. Performance studies using EVPFFT are performed based on domain decomposition over voxels of a periodic cell, which is a representative volume element (RVE) of polycrystalline copper. We begin by parallelizing the computationally intensive Newton–Raphson (NR) single crystal solver within EVPFFT. Next, we compare the performance of the serial and parallel FFTW (Fastest Fourier Transform in the West) using OpenMP (OpenMP-FFTW) and MPI (MPI-FFTW) with the original Numerical Recipes-based FOURN routine within EVPFFT. In the parallel environment, we find that the FFT calculations are best performed using the MPI version of FFTW. Finally, the remainder of the code, except read/write subroutines, is parallelized. Significant speedups of the original EVPFFT model are achieved using MPI on shared memory multicore workstations. Furthermore, results achieved on a distributed memory Cray supercomputer show promising strong and weak scalability and in some cases even super scalability for the single crystal NR solver in EVPFFT. MPI-FFTW also scales perfectly for microstructure RVEs larger than 643 FFT voxels. For example, the MPI-EVPFFT parallel version of the code accelerates the simulations for approximately two orders of magnitude using 64 cores over the old serial code for an RVE size of 1283. The parallel EVPFFT code developed in this work can run massive voxel-based microstructural RVEs taking the advantages of thousands of logical cores provided by more advanced clusters.
       
  • Efficient design optimization of complex system through an integrated
           interface using symbolic computation
    • Abstract: Publication date: December 2018Source: Advances in Engineering Software, Volume 126Author(s): Hansu Kim, Shinyu Kim, Taekyun Kim, Tae Hee Lee, Namhee Ryu, Kihan Kwon, Seungjae Min A complex system is composed of several subsystems and numerous lower level components. It is inefficient to design the complex system at the system level by using high-fidelity models. A system level approach using a language-based model is required to design such a highly complex system before implementing a detailed design. However, as commercial process integration and design optimization software packages focus on detailed design, which uses the high-fidelity models, it is difficult to perform the design optimization of a highly complex system, such as a combat vehicle. Moreover, as commercial optimization software packages use numerical computation, the gradient calculation cost can increase, and the matrix computation process can be inefficient in terms of optimization time. Therefore, in this study, an integrated interface for efficient design optimization was developed to focus on concept design using a MODELICA language-based model. Additionally, the design variable screening by using analysis of variance, surrogate modeling through sequential design of experiments, and symbolic computation were used to solve the aforementioned problems. These were applied to the design optimization of the combat vehicle system to demonstrate the effectiveness of the integrated interface and symbolic computation. In conclusion, a concept design utilizing a MODELICA language-based model was achieved, and the optimization time achieved by symbolic computation was largely reduced in comparison to the optimization time achieved by numerical computation.
       
  • A new multiscale phase field method to simulate failure in composites
    • Abstract: Publication date: December 2018Source: Advances in Engineering Software, Volume 126Author(s): R.U. Patil, B.K. Mishra, I.V. Singh, T.Q. Bui In this paper, a new multiscale phase field method (MsPFM) has been proposed to simulate crack propagation in composites. The MsPFM inherits the merits of anisotropic phase field method and multiscale finite element method. It is known that phase field simulation requires dense meshing to represent a sharp crack, thus the main aim of the MsPFM is to achieve mesh refinement in the vicinity of diffused crack/cracks. The proposed method is also used to study the interaction of a pre-existing crack with weak or strong interfaces (between matrix-fibre or between laminates) in terms of crack arrest, crack deflection, crack coalescence, and multiple cracks initiation in composites. Various numerical experiments are performed to demonstrate the effectiveness of proposed MsPFM to simulate the aforementioned failure characteristics of the composites. The crack growth trajectory obtained by the MsPFM for few test cases is validated through standard extended finite element method.
       
  • A Uniform-Gaussian distributed heat source model for analysis of residual
           stress field of S355 steel T welding
    • Abstract: Publication date: December 2018Source: Advances in Engineering Software, Volume 126Author(s): Tianci Li, Lele Zhang, Chao Chang, Liang Wei A novel combined heat source model is derived for the simulation of the residual stress field of a T welding. The model is derived combining Gaussian surface and uniform volume heat source, and is applicable to simulate welding process as the electric arc is moving across an angled structure. By both physical characteristics of T and arc welding process, one part of heat input is from the welding arc acting in the workpiece surface, the other is from the molten metal droplets. The two portions are accurately calculated by Gaussian surface heat source distribution and uniform volume source. The numerical simulation of the welding process for a S355 steel T welding based on this novel model has been done and obtain the transient temperature field, stress evolution and residual stress field of the structure. The comparison between measured results by the hole drilling and X-ray diffraction (XRD) and simulation indicates that the combined heat source is sufficient to allow for an overall prediction of the entire welding process of T joints.
       
  • Path-following interior point method: Theory and applications for the
           Stokes flow with a stick-slip boundary condition
    • Abstract: Publication date: Available online 8 July 2018Source: Advances in Engineering SoftwareAuthor(s): Tomáš Brzobohatý, Marta Jarošová, Radek Kučera, Václav Šátek A path-following interior point method is proposed for minimization of quadratic functions subject to box and equality constraints. The problems with the singular Hessian that is symmetric, positive definite on the null space of the equality constraint matrix are considered. The inner linear systems are solved by the projected conjugate gradient method preconditioned by oblique projectors. Numerical experiments include large-scale problems arising from the TFETI domain decomposition method applied for solving the Stokes flow with the stick-slip boundary condition.
       
  • Transformations of Arm-Z modular manipulator with Particle Swarm
           Optimization
    • Abstract: Publication date: Available online 27 June 2018Source: Advances in Engineering SoftwareAuthor(s): Machi Zawidzki, Jacek Szklarski A novel concept of hyper-redundant, snake-like manipulator is presented. It is based on the reconfigurable modular construction system–Arm-Z (AZ). AZ is comprised of linearly joined congruent modules with possibility of relative twist. AZ is an Extremely Modular System, i.e. it is composed of a single basic unit and allows for creating free-form shapes. Required level of usefulness and efficiency are among the most challenging design aspects of such reconfigurable systems. Here AZ is considered in the context of kinematics of robotic arms. In general, due to its highly non-linear nature, it is very difficult to find transitions between given states (configurations), especially under realistic environmental and structural constraints. As a way to control the manipulator, an implementation of Particle Swarm Optimization (PSO) for finding transitions between AZ states in realistic scenarios is proposed. Four practical examples are presented which are variations of two distinct problems: bending of a hexagonal AZ in a narrow slot (strong environmental constraints), and reaching a given point in 3D space by the tip of dodecagonal AZ (acting as a robotic arm). The problem of AZ transformation has been defined as a multi-objective optimization. The methodology is general with no restrictions to the objective function. Since the problem is strongly non-linear, in order to cover large space of potential solutions, the algorithm runs for a relatively large number of random initial swarms. This task was distributed on a computer cluster. Although the nature of AZ reconfiguration is discrete, the optimization algorithm is continuous.
