Title Dynamic Shear and Tensile Strength of Iron: Continual and Atomistic Simulation
Author(s) A.E. Mayer (Chelyabinsk State University, ul. Br. Kashiribykh 129, Chelyabinsk, 454078 Russia, mayer@csu.ru)
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.
Keywords high-rate strain, plastic flow, spall fracture, iron, molecular dynamics, continual theory of dislocations, fracture model
