Abstract

The failure wave phenomenon was interpreted in glass media under the high velocity impact. In view of the plate impact experimental observations, the progressive percolation of microfissures into the material bulk gives rise to the failure wave phenomenon which could be regarded as a diffusion process. The dynamic damage constitutive relation and nonlinear diffusion equation were established to describe the propagation of failure wave in glasses. Numerical results are presented and compared to lateral stress gauge measurements in shocked K8 glasses. It is shown that the proposed theory and simple model can capture the essence of the failure wave phenomenon.
