  • Vibro–Acoustic Analysis of the Strong Coupling System with an
           Elastically Restrained Rectangular Plate Backed by a Trapezoidal Cavity

      Authors: J. L. liao, H. C. Zhu, J. X. Hou, S. W. Yuan
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      The vibro–acoustic strong coupling problem between the panel and cavity widely exists in the industry. This paper developed a numerical method to study the natural characteristics and vibro–acoustic response of the strong coupling system with an elastically restrained rectangular plate backed by a trapezoidal cavity. The isoparametric transformation technique was used to normalize the trapezoidal cavity. The dynamical equations of the coupling system were derived using the energy principle and the Rayleigh–Ritz method with the Legendre polynomial series as trial functions. Then, the effects of structural boundary conditions and bevel angle on the natural frequencies of the system with the elastic plate on the top surface of the trapezoidal cavity were explored. The natural frequency increased with the number of structural support boundaries and the inclination angle of the trapezoidal cavity bevel. Besides, the steady-state response of the coupling system under different excitation conditions was investigated. Therefore, accurate prediction for steady-state response will provide ideas for noise control of the vibro–acoustic strong coupling problem.

  • Poro-Thermoelastic Waves in a Homogeneous Anisotropic Plate Plunged in the
           Inviscid Fluid

    • Free pre-print version: Loading...

      Authors: Vijayata Pathania, Pankaj Dhiman
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      This paper inspects the behavior of thermoelastic waves in the homogeneous, transversely isotropic plate containing voids immersed in the inviscid fluid in reference to the one-temperature generalized model of thermoelasticity. The basic governing equations for the solid plate have been developed in the context of the linear theory of poro-thermoelasticity. Helmholtz decomposition principle has been employed to solve the equations of motion for liquid. For the stress-free solid-liquid interfaces, the isothermal and thermally insulated boundary conditions have been applied simultaneously on the obtained solutions. The solutions of governing equations reveal that there exists a coupled system of waves namely thermal waves, void wave motion, and elastic waves, and a decoupled purely transverse wave. Apart from that, one mechanical wave in each liquid layer also exists. The secular equation for anti-symmetric and symmetric modes of vibration has been derived which better explains wave motion. To unveil the wave characteristics, the numerical–functional iteration technique has been employed for generating numerical data and results have been validated by tracing out the various graphs. The effects of temperature change, as well as voids in the solid plate and inviscid liquid in the neighborhood of the plate, have been noticed on phase velocity, attenuation coefficient, etc

  • The Problem of Wedge Indenter with Flat-Rounded Bottom Indenting
           Half-Plane Elastic Body

    • Free pre-print version: Loading...

      Authors: Bo Liu, Ting Li, Yanhui Han, Yanqing He, Chunqing Fu
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      In this paper, the problem of a wedge indenter with flat-rounded bottom indenting an infinite half-plane elastic body is solved. It can be used to study the penetration force or the surface stress distribution of the cutter when the tool intrudes into an elastic body. First, a first-order continuity method is proposed to eliminate the stress singularity caused by the sharp corners of the wedge indenter with flat bottom. The two-dimensional elastic contact problem is transformed into a Riemann–Hilbert boundary value problem with discontinuous coefficients expressed in the form of complex variables. For the frictionless contact problem, the explicit analytical solution is obtained for contact stress on the half-plane surface. Furthermore, the expression of the stress potential function is also derived to solve the stress field in the half-plane. Verification indicates that the wedge indenter with flat-rounded bottom can degenerate to several well-studied shaped indenters, including the Hertz model and flat-rounded model. The model in this paper is also validated with its numerical counterpart built in the finite element program LS-DYNA. Finally, the sensitivity of different configuration parameters on the normal contact stress and interior stress field in numerical model was investigated.

  • A Novel Methodology for Non-Destructive Characterization of
           Polymers’ Viscoelastic Properties

    • Free pre-print version: Loading...

      Authors: Andrea Genovese, Antonio Maiorano, Riccardo Russo
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      A procedure of non-destructive experimental tests aimed at determining the viscoelastic characteristics of the rubbers is described. After recalling the basic principles of viscoelastic theory, the experimental setup and the measurements necessary for the test are described. The procedure consists in hitting the surface of the object under test with a specially instrumented indenter. The techniques for processing the acquired signals to identify the characteristic starting and ending points of indentation in the time-histories are then illustrated. By analyzing separately the phases of the free drop of the indenter and the phase of contact between indenter and rubber, the main mechanical characteristics, such as stiffness and damping of both the instrumented indenter and the bulk of rubber under test are estimated. The methods of calculating the viscoelastic parameters of the rubber starting from the knowledge of the above mechanical parameters are then illustrated. The determined results, in terms of storage and loss moduli, are compared with those provided by classic DMA type tests. The qualitative agreement is excellent. The quantitative agreement falls in the scattering range typical for this kind of measurement. The paper is completed with a discussion of the main causes of measurement uncertainty.

  • On The Vibration, Buckling and Dynamic Stability of Three-Directional
           Functionally Graded Circular Cylindrical Tubes with Consideration of
           Higher-Order Beam Theory

    • Free pre-print version: Loading...

      Authors: Ye Tang, Zhi-Sai Ma, Qian Ding
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      In view of engineered structures such as those of advanced aircraft and space shuttles are often required to withstand multidirectional loads. We present three-directional (3D) functionally graded materials (FGMs) to reconstruct circular cylindrical tubes placed on an elastic foundation, and the buckling, dynamic and stability behaviors are investigated. In contrast with those of unidirectional and bidirectional FGMs, the material properties of 3D FGMs are designed to vary continuously and smoothly in three directions to fulfill multifunctional requirements. Considering the higher-order beam theory, Hamilton’s principle is adopted to establish the governing equations with variable coefficients of the 3D FGMs tubes. The generalized differential quadrature method (GDQM) is used to predict the statics and dynamics. Numerical simulations are performed to obtain the effects of physical parameters, such as the 3D FGM indexes, on the natural frequency, buckling load and stability regions in detail. The results show that the mechanical behaviors of the circular cylindrical tubes can be easily tuned by introducing 3D FGMs, demonstrating that 3D FGMs have more potential than one-directional and two-directional FGMs in terms of improving the load-bearing capacity of structures and optimizing those structures.

  • Thermoelastic Theories on the Refracted Waves in Microstretch
           Thermoelastic Diffusion Media

    • Free pre-print version: Loading...

      Authors: S. S. Singh, Sanjay Debnath, Mohamed I. A. Othman
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      This work investigates the outcomes of three thermoelastic theories on the reflection/refraction of elastic waves due to incident, coupled longitudinal and coupled shear waves from a plane interface between two microstretch thermoelastic diffusion solid half-spaces. The propagation of seven basic waves consisting of five longitudinal and two shear waves has been explored using the boundary conditions. The amplitude and energy ratios of the reflected and refracted waves are obtained analytically and numerically for the incident coupled longitudinal and coupled shear waves. We have seen that the longitudinal wave corresponding to micropolar does not reflect and refract from the interface. The variations of these ratios with respect to the angle of incidence based on GL theory, LS theory and CT theory are depicted for a particular specimen. The amplitude and energy ratios of the reflected and refracted coupled longitudinal waves for the incident, coupled longitudinal waves decrease with the increase of the angle of incidence. Some special cases have been deduced from the present formulation.

  • Nonlinear Thermo-Mechanical Response of Bi-Directional Functionally Graded
           Porous Beams with Initial Geometrical Imperfection

    • Free pre-print version: Loading...

      Authors: Qiao Zhang, Hu Liu
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      In this paper, the nonlinear vibration and buckling of bi-directional functionally graded (2D-FG) beam subjected to thermal loading are examined via the higher-order shear deformable beam theory incorporating the von Kármán geometric nonlinearity. Two types of initial defects including the internal porosity distribution and external geometrical imperfection shape are taken into consideration. The temperature-dependent material property varying along the length and thickness following the power-law function is employed, and the porosities inside the 2D-FG beam with even and uneven distributions are considered. The initial geometrical imperfection is described by the product of trigonometric and hyperbolic functions, which can capture both global and localized imperfection shapes. The discrete equations of motion for the 2D-FG beam are established by using the differential quadrature method (DQM), and the derived function is solved by an iterative procedure. The nonlinear thermo-mechanical vibration and buckling of 2D-FG beams under uniform, linear, and nonlinear temperature loads are systemically compared. Moreover, several key factors such as 2D-FG indexes, porosity distribution, geometrical imperfections, as well as boundary conditions are investigated in detail. The proposed model and obtained results can be used to guide the optimization design of multi-functional and multi-graded materials serviced under thermal environment.

  • Molecular Dynamics Simulations of Nanoindentation of CuNi Alloy

      Authors: Ben Han, Can Zhang, Mingxing Shi
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      In this paper, molecular dynamics was used to simulate the indentation process of copper–nickel (CuNi) alloy. Its mechanical properties and behaviors were investigated focusing on factors such as indentation velocity, test temperature and crystal orientation. Generally speaking, dislocation generations and slips, stacking faults, extended dislocations and deformation twins, one or more of them come into play the dominant role during plastic deformation, which in return leads to an improved or reduced hardness of CuNi alloy. Specifically, simulations and analyses reveal the following: (1) its hardness [math] increases with [math] increasing, but the reduced elastic modulus [math] is not sensitive to [math]; when it comes to test temperature [math], both [math] and [math] are reduced at elevated [math]; besides, the CuNi alloy along [math] owns the highest [math] and [math], the value of [math] along [math] is slightly smaller than that along [math] (2) the dislocation density [math] varies severely in the early stage of indentation and then generally levels off when indentation depth reaches approximately 1.5[math]nm; by and large, its hardness and dislocation density follow the classical Taylor hardening model and the hardening coefficient does depend on the three factors; (3) the plastic-zone size parameter [math], when [math] or equivalently [math] can be taken as constant roughly 4.0 except in the case of indentation along [math], in which it is about 5.7.

      Authors: Seyedeh Samaneh Asemani, Gholamhossein Liaghat, Hamed Ahmadi, Yavar Anani, Sahand Chitsaz Charandabi, Amin Khodadadi
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      This study proposes a new theoretical model for high-velocity impact in two kinds of targets, Kevlar/elastomer and Kevlar/epoxy composites, and comprehensively discusses and compares these. In this analysis, with the aid of hyperelasticity theory, energy absorption equations are derived based on the linear and nonlinear behavior of constituents to assess the dependence of the ballistic limit on the interaction of the first, second, third, and fourth layers of the laminate on each other. Furthermore, to investigate the matrix effect on the in-plane shear, tensile tests were performed at [math] direction for both Kevlar/elastomer and Kevlar/epoxy composite laminates. The results indicate that the adhesion of Kevlar fibers to the rubber matrix is more substantial than their adhesion to the epoxy matrix, increasing the failure shear strain of elastomeric composites and reducing the debonding between the fiber and the matrix which led to greater ballistic velocity. The results of the experimental tests verified the proposed model and confirmed its precision. With this verified model, the thickness effect on the ballistic behavior of the targets was investigated.

      Authors: Ashraf M. Zenkour
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      Different subjective developments of the multi-time-derivative (single/dual/triple)-phase-lag heat formulae have been examined in this paper. A unified theory of coupled photo-thermoelasticity is defined to investigate both delay phase-lag times of the temperature gradient and the heat flux as well as the third delay phase-lag time of the thermal displacement gradient. Some unique issues that contain a lot of formulae have been considered to manage all the thoughts about models in the literature. The straightforward and refined Tzou’s multi-time-derivative (single/dual/triple)-phase-lag, Lord–Shulman, Green–Lindsay, and classical theories are all investigated. Moreover, Green–Naghdi of type II, as well as type III models of generalized thermoelasticity with and without energy dissipation, have been attained in simple and modified formulations.

  • Free Vibration Analysis and Numerical Simulation of Slightly Curved Pipe
           Conveying Fluid Based on Timoshenko Beam Theory

    • Free pre-print version: Loading...

      Authors: Jia-Rui Yuan, Xin Fan, Song Shu, Hu Ding, Li-Qun Chen
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      The modeling of a slightly curved pipe conveying fluid usually adopts the Euler–Bernoulli beam theory. In this paper, a dynamic model of the slightly curved pipe conveying fluid based on the Timoshenko beam theory is established for the first time. The complex mode method is used to obtain the frequencies, the modes, and the first critical velocity of the slightly curved pipe. Two kinds of initial configurations of the pipe with fixed–fixed boundary conditions are studied. Based on the Galerkin truncation method, the natural frequencies of the slightly curved pipe are also obtained with the generalized eigenvalue method. Moreover, the Coriolis force caused by the fluid is equivalent to the damping matrix. Therefore, a novel finite element model of the curved pipe considering fluid influence is developed. The numerical simulation method is extended to calculate the mode and frequency of the slightly curved pipe. Numerical results show that all the three methods have high accuracy when calculating the natural frequencies of the transverse vibration of the slightly curved pipe conveying fluid. However, the developed finite element method does not show the effect of flow velocity when determining the modes. Moreover, the initial bending cannot be ignored when analyzing the vibration characteristics of the slightly curved pipe conveying fluid.

  • Analytical Approach to the Coupled Effects of Slope Angle and Seepage on
           Shallow Lined Tunnel Response

    • Free pre-print version: Loading...

      Authors: Nannan Zhao, Zhushan shao, Bo Yuan, Xinyuan Chen, Kui Wu
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      The existing analytical models of shallow lined tunnels pay little attention to the coupled effects of slope angle and seepage, leading to an overestimation of tunnel stability. In order to overcome such a problem, based on the methods of coordinate transformation, complex function and conformal mapping, we attempt to provide an analytical approach to estimate the effective stress and deformation in shallow lined tunnels considering the corresponding influence factors in this study. First, the stress function is extended to the Laurent series in the complex plane, followed by Laplace transform and inverse transform methods on stress function, and the analytical solutions for stress and displacement fields around the tunnel are achieved during different stages. Then, Mein–Larson formula and G–A formula are used to obtain the pore water pressure and effective stress of surrounding rock and lining, considering the effects of rainfall and groundwater. The analytical solution provided in this study can be reduced without considering the lining support and slope angle effects. Furthermore, the rationality and effectiveness of the proposed solution are achieved by a comparison of numerical results. Finally, a comprehensive parametric investigation based on the proposed solution is performed, including buried depth, slope angle and rainfall intensity. The results show that the small change of stress and deformation of the ground surface is observed as the buried depth becomes more than 30[math]m. If the slope angle varies within a range from 0 to 30[math], the influence of slope angle change on the stress and deformation of surrounding rock can be generally neglected. When the rainfall intensity is greater than a certain threshold or rainfall time is shorter than a value, these two parameters are in a limited effect on the seepage change.

  • Behaviors of Composite Laminates Under Low-Energy Impact Using A Novel
           Analytical Framework

    • Free pre-print version: Loading...

      Authors: Xuecheng Han, Hongneng Cai, Jie Sun, Zhiyuan Wei, Yaping Huang, Lingqi Meng
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      Carbon fiber-reinforced polymer (CFRP) composite laminates have the characteristics of orthogonal anisotropy and heterogeneity, so the failure mechanism under low-energy impact is very complex. As a supplement to the experiment, it is necessary to develop numerical tools to predict the mechanical behavior of composite laminates under low-energy impact. In this paper, the mechanical behavior analysis framework of composite laminates under low-energy impact load is established by using the micromechanics of failure (MMF) theory and the mixed mode exponential cohesive zone model (CZM). The failure modes of intralaminar components in composite laminates are determined by MMF theory. The damage onset and evolution process of interlaminar delamination is described by the mixed mode exponential CZM. The finite element model of composite laminates under low-energy impact is developed using the Python scripts on ABAQUS/Explicit platform. The user-defined material subroutine VUMAT is written in Fortran language. The impact responses of composite laminates with several impact energies are predicted. The intralaminar failure modes and interlaminar delamination behavior are discussed in detail. The results show that the tensile failure of matrix and interlaminar shear delamination failure are the main failure modes of composite laminates under low-energy impact load. The experimental results present better consistency with the numerical analysis, indicating that the constructed multiscale analysis method is efficient and accurate. This study expands the analysis method of mechanical behavior of composite laminates under low-energy impact. The constructed mixed mode exponential CZM also has guiding significance for the failure analysis of other bonding materials.

      Authors: Vasily Golubev, Alexey Shevchenko, Nikolay Khokhlov, Igor Petrov, Mikhail Malovichko
      Abstract: International Journal of Applied Mechanics, Ahead of Print.
      This paper considers numerical simulation of acoustic waves in heterogeneous two-dimensional (2D) media by the grid-characteristic method. We present a novel high-order compact numerical scheme that accurately handles discontinuous material parameters. We present one-dimensional and 2D formulations and discuss their programming implementation. The merits of this approach are evaluated in numerical experiments. It is verified empirically that the scheme demonstrates the second-order of convergence. Furthermore, we apply the scheme to the Sukhoi Log gold deposit model and the Marmousi model. The primary practical outcome of this research is that it provides a tool for precise simulation of wavefields in complex media with discontinuous parameters.
