In this paper, the attitude changes of projectile and its influence parameters during the process of penetration on the ship plate structure are studied by material point method. The method is firstly verified by comparing with experimental results. The numerical results agree well with the experimental results. The failure behavior of the plate is similar to the actual situation, and the failure mode is basically the same. With the change of different parameters, the attitude of projectiles will change differently. The greater the penetration velocity, the weaker the influence of other related parameters on the projectile attitude. When other parameters are not changed, the relative size of the strength of stiffener and the thickness of target plate determines the change of the projectile attitude. Analyze from the perspective of energy and force, and finally projectile attitude can be divided into four types.
