Abstract
Appropriate model and space discretization were chosen to simulate the loading process of specimens conducted on the Split Hopkinson Pressure Bar (SHPB) in two-dimension, and the adiabatic shear deformation course of the hat-shaped specimen under high strain rate was obtained. Based on the criterion of the formation of adiabatic shear to Stress Collage, the rule of adiabatic shear deformation was analyzed, the simulated stress-time curves and strain-time curves were employed to calculate the temperature field, the type of the shear bands was determined, and the results of numerical simulation are consistent with the experimental results.
