Numerical Simulation for Overload Characteristic Dynamic Mechanical Property of the Ammunition into Concrete Targets
By building the structure of projectile and target, the penetration model and the force environment and initiation criterion of explosive were analyzed. Using the simulating software ANSYS/LS-DYNA, adopting of the corresponding ammunition and target model, and the process of the ammunition penetrate the concrete was simulated and computed, the curves of projectile and explosive were got respectively. And the result of projectile was contrasted with the date of the Forrestal model, the result of overlode and trend were anastomosised to the model. Moreover the overlode characteristic of explosive was predicted, the simulated results are creditable, they could give some reference to the scheme design of the like penetration of ammnnition.
