چکیده
* Presented as Paper IEPC-01-49 at the 27 International Electric Propulsion Conference, Pasadena, CA, 15-19 October, 2001. † Copyright © 2001 by the authors. Published by the Electric Rocket Propulsion Society with permission. Modeling the Hall thruster for sputter yield prediction is of considerable interest to the electric propulsion community. This paper documents the status of a finite element based computational development for modeling unsteady plasma flow in the acceleration channel of a stationary plasma thruster (SPT). The results are validated with the available test data and compared with the reported results of particle-in-cell (PIC) method in the literature. Computational challenges are discussed. The lifetime issues also are considered.

Introduction: Because of the importance of vertebral compressive fracture (VCF) role in increasing the patients’ death rate and reducing their quality of life, many studies have been conducted for a noninvasive prediction of vertebral compressive strength based on bone mineral density (BMD) determination and recently finite element analysis. In this study, QCT-voxel based nonlinear finite eleme...
متن کاملFinite Element Modeling of Strain Rate and Grain Size Dependency in Nanocrystalline Materials
Nanocrystalline materials show a higher strain-rate sensitivity in contrast to the conventional coarse-grained materials and a different grain size dependency. To explain these phenomenon, a finite element model is constructed that considers both grain interior and grain boundary deformation of nanocrystalline materials. The model consist of several crystalline cores with different orientations...
