【Abstract】

<正>In this paper,we used HJC model for concrete and self similar arithmetic to modify the spherical Cavity Expansion Theory for concrete.Comparing with the experimental data,the numerical results indicated that,the modified Cavity Expansion Theory can be well utilized at the prediction of penetration depth.At this point,the force and rigid motion analysis for two types of projectiles were conducted.
