Abstract
In order to study the effects of the wall thickness, plug block length and shell steel yield strength of the Penetrator with Enhanced Lateral Effects (PELE) on the opening size of the intrusion concrete target plate, Autodyn software was used to model and simulate the target system. Through simulation, it is found that with the reduction of PELE wall thickness, the pore diameter is gradually increasing. The results show that when the wall thickness of the shell is C-3, the plug length is D mm, and the steel strength of the shell is 900kpa, the opening diameter of PELE is 358mm, which is 40.9% higher than that of the original model.
