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.

Finite Element Prediction of the Behavior of Profiled Steel Sheet Dry Board Folded Plate Structures an Improved Model (RESEARCH NOTE)

This paper describes an alternative finite element model that would yield more accurate results in the prediction of the behavior of Profiled Steel Sheet Dry Board (PSSDB) folded plate structures, which can be considered as an improvement of an earlier proposed model. The PSSDB folded plate structures are being proposed as an alternative to traditional forms of roof construction.The PSSDB syste...

Finite 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...
