Abstract
The damage characteristics of rock were brought out by penetrating-exploding test of SAP, and the effect factors were analyzed, which should be taken care in numeric simulation of weapon effect. Based on the hydro plastic-elastic model, a new constitutive model for rock was proposed. The compressing effect can be obtained by the equation of sate, and the damage cumulation can be got by JHR-TCK equations, thus all the factors of penetration and explosion effect of SAP are taken into account. At last, the test results and simulation data were compared.
