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

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.
