Abstract
Based on the features of underground explosion-induced wave, a new elastoplastic continuously damaged constitutive model was developed. The damage evolution equations and the yield functions for the model were established on the basis of different deformation behavior, and both the effects of distortional dilation and damage softening were included. The results of numerical simulations for underground explosion-induced wave indicate that the proposed model is effective and available.
