Numerical realization of probabilistic model of composite material taking into account the damage evolution at high impact velocities

Abstract
A numerical simulation of strength of plates of a fiber-reinforced multicomponent composite material under impact with collision velocities ranging from 20 to 1500 m/s was made using the probabilistic model within the framework of the finite element method. Peculiarities of the process of energy absorption and plate damage dimensions depending on the impact velocity are analyzed from the point of view of key physical damage processes. A comparison of numerical results and experimental data on research of damage of composite plates after impact was carried out.
