摘要：
The probability damage and fracture model for a composite material under impact loading is proposed, within this model, the damage parameters are regarded as the probability functions of strain, strain rate, and temperature with a preset probability density. FEM numerical strength computations for fiber-reinforced plates were carried out in the range of impact velocities up to 1200 m/s. The dynamics of energy absorption and plate damage levels with the impact velocity were analyzed.
