New Modelling Approach for Micromechanical Modelling of the Elastoplastic Behaviour

Abstract:

A new theoretical approach is developed to simulate the elastoplastic behaviour in cubic alloys during various strain-path changes. The polycristal is considered as a composite consisting of hard dislocation walls of high local dislocation density which are separated by soft regions of low local dislocation density. The improved elasto-plastic self-consistent method is applied to deduce the global behaviour of the aggregate. The model is tested by simulating the macroscopic behavior and the development of intergranular strains during different complex loads.
