To study the stress change rule of the charge of projectile penetrating hard target, the numerical calculation for the pressure changes and plastic deformation of charge generated in projectile penetrating aluminum alloy target process were carried out by using LS-DYNA dynamic analysis software. The pressure changes and unit deformation occurred on the observation points were analyzed. The results indicate that the plastic deformation and ignition in head explosive in penetrating process are mainly caused by high compression. With the improvement of projectile velocity, alternative actions between compressive load and tensile load gradually transit to tensile load which plays a main role in tail explosive. Its edges are mainly destroyed by shear load, leading to damage of the charge. The loading stress of central explosive is low, having lesser damage. The experimental results verify the rationality of the simulation.
