Abstract

In this paper, continual and atomistic simulations are used to investigate the shear and spall strength of iron under high-rate strain conditions. The continual simulation is based on the use of models of dislocation plasticity and fracture due to formation and growth of microcracks and cavities; the molecular-dynamic simulation is based on the use of the LAMMPS software. The obtained results are analyzed in the light of experimental data for the high-speed impact and irradiation of iron films by ultrashort pulses of intense laser radiation.
