Simulation of meso-macro dynamic behavior using steel as an example

Abstract

Presented in this paper is a model, where strain hardening and strain rate sensitivity are taken into account. The cellular automata rules are included into a continuum mechanics formulation to describe shear band propagation at the mesoscale. We apply the model in simulating deformation of the 20MnMoNi55 steel as an example. The macro stress-strain behavior and plastic strain patterns at the mesolevel are analyzed in the course of a computational tension test.
