Abstract: Destruction of ceramic barriers under an axisymmetric high-velocity impact has been studied experimentally. The results of the investigations testify to the existence of a significant influence of the structure of ceramic materials on the process of their destruction. The process becomes asymmetric, which can lead to rotation of the impactor with conservation of its initial direction of motion. There are still no models describing the asymmetric character of high-strength ceramic destruction. The probabilistic approach to describing strength characteristics of materials is a possible approach to creating such models.
