Study on fragmentation of PELE against thin targets

The fragments mass and size from penetrator with enhanced lateral effect (PELE) perforating thin rolled homogenous armor (RHA) target was characterized through theoretical and numerical methods. An analytical model based on energy-limited spall (ELS) was proposed to predict fragments mass distribution of PELE with different cores and impact velocities. For different cores the expansion can be represented by a scaling factor l in the analytical calculation. The explicit finite-element (FE)-analysis of PELE f...
