A probabilistic approach for fragmentation of brittle materials under dynamic loading
Dynamic loadings produce high stress waves leading to the fragmentation of brittle materials such as ceramics. The main mechanism used to explain the change of the number of fragments with stress rate is an obscuration phenomenon. After the presentation of a probabilistic approach, the evolution of the number of nucleated flaws and a damage model are derived.
