Abstract

This paper presents a study on the multi-spall of ductile metal induced by triangular impulse, using the simple cut-off pressure model and Tuler-Batcher's accumulative damage model to describe the spall. Numerical results show that the spall thickness increases with increasing ratio of pulse length to strength of shock wave and the destroy depth of the target approximates to half of pulse width under extreme loading.
