摘要：

The finite element method (FEM) is a very powerful device for solving many continuum mechanics problems which can be treated neither theoretically nor experimentally. In this paper FEM is developed for the analysis of semi-microscopic effects within plastically deformed multicrystalline metals. The suggested numerical procedure is based on the model of the thermo-activated motion of dislocations which is responsible for inelastic time-dependent deformation. A comparison between numerical and experimental results for activated slip systems is presented. © 1990.
