多結晶体の非弾性挙動の統一形構成方程式による有限要素法解析モデル

抄録

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 semimicroscopic effects within inelastically deformed polycrystalline metals. The suggested numerical procedure is based on a model of the thermoactivated motion of dislocations which is responsible for inelastic time-dependent deformation. A comparison between numerical and experimental results for an activated slip system is presented.
