Abstract

In the paper we discuss the construction, method of realization, and approval of a new dynamic response function for movable cellular automata, which depends on loading velocity. The proposed method is based on analytical relations obtained in analyzing a dynamic model of the uniformly deformed material with defects, which is developed within the gauge theory with consideration for energy dissipation and defect self-action. The response function is realized numerically by introducing the time dependence that determines the transition from the elastic to the plastic domain with an increase in yield stress as strain rate rises. The response function is approved using uniaxial loading simulation.
