Model calculating high-speed collisions between bodies with different shapes and massive metallic obstacles

详细

The mathematical model of a high-speed collision between bodies with arbitrary elongation and massive metallic obstacles has been suggested. The model is based on the energy balance and stage-by-stage scheme of formation of a crater. The collision process has been considered to be the quasi-stationary penetration of the deformed impactor and inertial deepening of a crater at the final step. A comparison of the calculations with the results of numerical simulations and physical experiment has shown satisfactory agreement.
