Preliminary simulation sty of explosive charge damage during projectile penetration with the DDA method

摘要：

　　In this paper,a numerical modeling technique based on the discontinuous deformation analysis(DDA)method is used to simulate the dynamic damage process of explosive charge in a projectile during penetration.A newly improved sub-block fracturing modeling method together with a newly developed element elimination algorithm is used to simulate the damage of the charged explosive as well as the failure of the concrete target.A modeling example is given.The penetration of a projectile into the target and the dynamic response and damage process of the explosive charge are numerically reproduced and analyzed preliminarily.
