| Abstract: | The plugging failure for strain-hardening metallic plate struck normally by a rigid conically-nosed projectile was investigated. On the basis of two-phase engineering model for ideal elastic-plastic material, the analytical formula of the critical semi-angle of the projectile nose and the corresponding ballistic limit velocity for the train-hardening material target were gained . The effects of nose length, projectile mass, and the mechanic performance of plate material on the plugging failure were analyzed. The resuits of the present model are in good agreement with those published previouslly. |
