Аннотация

A hybrid discrete-continuum Excitable Cellular Automata (ECA) approach is proposed to study the vector character of the mass and energy transfer flows in a solid under high-rate loading. Based on the torsion energy calculations, the model of generation and accumulation of defect structures is proposed. Numerical simulations of uniaxial shock loading of specimens with three typical notch shapes are performed to validate the proposed approach. It is shown that stress relaxation occurs most effectively when the modulation of various components of the force moment takes place at various scales. This offers the possibility to reduce the stress concentration substantially by tailoring the materials microstructure.
