Experimental and Computational Investigation of the Fundamental Mechanisms of Cratering
Early attempts at estimation of stress wave damage in blasting by use of finite element analysis met with limited success due to numerical instabilities that prevented calculations from being carried to late times._x000D_
An improved damage model based on microcrack growth in tension allows finite element calculations which remain stable at late times._x000D_
Estimation of crater profiles for blasting experiments in granite demonstrate successful simulations with this model.
