  • Combining the simulation with the experimental results of the penetration process of penetrator with enhanced lateral effect (PELE) in metallic target, the process of the shell expansion can be divided into two stages, the accelerating expansion and the uniform expansion.Based on the model of the damage function by Feng Jiabo, we obtained the damage and fracture evolution equation responsible for the shell of PELE.According to the damage evolution equation responsible for the shell of PELE, the fracture process parameters of PELE were calculated.Moreover, the relationship between shell fracture critical strain and velocity of the projectile was analysised, which is useful in engineering design of PELE.
