  • The Role of Electrostatic Forces in the Generation of Ion Propulsion

    • Authors: Tomas A. Pribanic; Xiangyang Zhou
      Pages: 1 - 8
      Abstract: This document presents a study on the contribution of the electrostatic force in the generation of thrust using an asymmetric electrodes configuration subjected to a high potential differential. The study uses computational models to provide an optimized configuration which generates 296.99% higher levels of electrostatic force when compared to a baseline configuration. Experimental testing of a system having comparable geometries and potential differentials to the computational models are conducted. The computational models are then compared to empirical results from the experimental tests. Results show a decreased in thrust with an increase of electrostatic force down to 61.58%. The discrepancy between the computational and experimental results is investigated by conducting a third experiment having an experimental set-up with multiple independent structural supports. The use of multiple independent supports shows and increase of internal forces of 69.23%. It is then concluded that the optimized experimental set-up increases the electrostatic repulsive forces between electrodes having common electric charges, but it does not translate into an increase in thrust. Instead, the increase in electrostatic force using the electrodes configurations used in this study shows a deleterious effect in thrust levels generated using an asymmetric capacitor configuration.

  • Determination of the Stress Intensity Factor with an Empirical Approach
           for Circular and Elliptical Cracked Sections

    • Authors: Hicham Laribou; Chadia Qotni
      Pages: 9 - 16
      Abstract: In the industrial field, the control of the structural integrity of a cracked metal part remains a capital maneuver in the prediction of failures in order to accurately define the functional lifetime of these parts. In this case, the Stress Intensity Factor (SIF) plays a central role to assess the damaging of a crack in a structure under a given loading. The purpose of this paper is to examine and check the analytical calculation of the SIF through an empirical approach of the form factor with those computing in mode I, using in the linear elastic domain, by the finite element method with ABAQUS software for two different cracked sections. The first defect studied in this work has a form of a circular section with a central crack under uniform tensile load. The second defect has a form of elliptical section with a central crack under uniform tensile load. The form factor function Y used, remains the main element for the analytical stress intensity factor determination. For each form of section, the obtained results were examined by comparing with the results given by the ABAQUS software. Indeed, after examination, the model was finally approved and validated for the circular section, on the other hand, it couldn’t be validated and adopted unfortunately in the elliptical case.

  • Standard Guardrails and Related Systems – Challenge and
           Opportunities

    • Authors: Ralph L. Barnett
      Pages: 17 - 27
      Abstract: Safety fences define safe from unsafe regions and safeguard against falls into such regions. Standards define their required strength and stiffness and specify critical aspects of their geometry. It is implicit that the community of users of safety fences are responsible adults with the further understanding that all ambulatory humans can willfully breach these structures. Despite their de minimis design constraints, technologists have not understood nor met the safety challenges posed by these simple, classical, and ubiquitous structures. The purpose of this paper is to identify a few of the safety shortcomings of fence technology which include the fundamental problem of anthropometric guarding, improperly written standards, the challenge of corrosion, dangerous testing protocols, and the creation of testing hardware.
