Abstract
Considering the compression as well as the dilatation of the concrete, a theory of dynamic cylindrical cavity expansion was proposed, where the complete response of target included densification region, dilatation region, crack region, elastic region, and the dilatant-kinematic relation was used in the dilatation region. A relation between the cavity stress and the expansion speed was got based on the theory, and according to the relation both the depth of penetration and the acceleration were calculated. The research indicates that the calculated results based on the theory fit well with the experiment data, and the model can predict the penetration ability and the acceleration of the projectile with CRH=6 well.
