Model of the Deformation and Fracture of a Metal Ceramic Based on TiB2 + B4C upon Dynamic Loading

摘要

In the case of high-speed collisions, ceramic materials based on refractory compounds are brittle and unreliable. A promising direction for improving the physical-mechanical characteristics of ceramics operating at high pressures and temperatures is the introduction of an efficient metal matrix into their content. A reliable tool for designing materials with a given directivity of properties is a computational-experimental method based on the mathematical simulation of shock wave processes and experiments. A mathematical model describing the deformation and fracture of a metal ceramic based on titanium diboride and bore carbide (TiB2 + B4C) with a metal matrix upon dynamic loading is proposed in this work.
