Computer simulation of catching of explosively propelling metal fragments by protective casing

In the paper a mathematical-physical model, results of computer simulation of the propelling of metal fragments by pressure of detonation products and their catching by the protective casing made of a quasi-aramide fabric have been presented. The impact on the protective casing due to shock waves generated by the explosion has been examined. Depending on the nature of the issue, the 2D free particles or 1D Lagrange method has been used in the computer simulation.
