Abstract

Abstract

The spall properties of no-Co-alloy steel loaded by gas gun are studied, and Hugoniot elastic limit, spall strength, spall thickness and plastic strain rate are obtained from each experiment. By the fracture analysis and metallographic analysis, we obtained the spall fracture mechanism at different strain rate. In addition, the spall fracture is simulated by LS-DYNA dynamic finite element code, and the simulation results agree well with that of the experiments.
