By analyzing the structure of the warhead and target, credible analysis method was chosen, and the damage effect of the semi-armour piercing and penetrate-blast minitype warhead destroying the multi-layer target was analyzed in theory. Using the computing software AUTODYN-2D, the optimization mathematic model was built, and the damage process of penetrating and blasting was simulated, and then the results were contrasted with the data of some correlated live ammunitions . Each group of data shows that, unde...
