To take into account compressive damage in ceramics during a high-energy impact, we first analysed the degradation mechanisms of two SiC grades under quasi-static uniaxial compression. This paper deals with an experimental approach, post-mortem investigations and a probabilistic treatment of the results. A numerical investigation of these tests is performed to understand the phenomenology and explain the results.
