【Abstract】 In this paper, we developed a model that can describe the process of projectile with spherical nose penetrating limited thickness targets. Penetration force can be calculated on the basis of the theory of dynamic spherical cavity expansion approximation. On the theory of continual damage mechanics, the time when extrusion occurred can be taken and the length of extrusion also can be given too. Finally some penetration calculation results about a tungsten sphere to aluminum limited thickness targets are presented to validate the reliability of the method.更多还原
