    Abstract
  • A crystal plasticity finite element model combined with equation of state was built to simulate the dynamic elastic-plastic large deformation behavior of <100> LiF under high-rate shock loading. The characterization of the stress wave profile, the patterns of the dynamic mechanical evolution and their essential causes in view of the continuum mechanics were obtained through simulations, with the following results achieved: (1) the wave profiles of millimeter-sized specimens exhibit elastic-plastic two-wave response, elastic precursor decay and stress relaxation below 15 GPa; (2) in view of continuum mechanics, the stress relaxation is essentially due to the viscous plastic flow which accounts for the increase rate of the total strain being less than that of the plastic strain, and which further reduces the elastic strain and pressure; (3) the third derivative of pressure to time being greater than zero was proposed as a criterion for estimating the critical pressure of the two-wave and the one-wave response of the stress wave profile, and the estimation result indicated that the critical pressure increased with the increase of the doping concentration in specimen; (4) the effect of temperature rise during the high-rate shock deformation is non-negligible, and the elastic volumetric deformation contributes to most of the temperature rise.
