ANALYTICAL MODEL OF DEFORMED PROJECTILE PENETRATING INTO CONCRETE WITH CORUNDUM-BOULDER MATRIX

Based on the disfeaturement of the projectile measured in experiments and in virtue of Taylor theory, a simplified analytical model of a deformed projectile penetrating into concrete target with corundum-boulder matrix was put forward. The deformation of the target was taken into account. The predicton formula for penetration depth, and displacement and velocity time history of projectile tails were deducted. The calculaton results by using Runge-Kutta numerical method are in good correspondence with the high-speed camera test data.
