Abstract

The adiabatic shear behaviour of a specimen is observed, based on a series of numerical simulations of SHPB test using 921A steel pure shear hat-shaped specimens in the present paper. The initiation and the propagation of an adiabatic shear band (ASB) and the relative distribution of temperature field in the specimen are analyzed. It is found that ASB is formed as the spread of an unstable zone with high temperature and high strain in the two ends of the Shear Zone. The spread speed of an ASB is related to the loading rate V0, whilst the width of ASB is nearly independent of the loading rate. All the ASBs are deformed bands corresponding to various values of V0.
