A Cracked-Comminuted Response Model of Confined Concrete Based on Griffith Strength Theory

Abstract:

A dynamic spherical cracked-comminuted response model was proposed for the penetration into confined concrete targets with finite radius and lateral elastic confinement. The material was described by linear pressure-volumetric strain relation and Griffith strength theory in the comminuted region, and described as incompressible in the cracked region. Numerical results show that the cracked-comminuted interface velocity and the cavity expansion stress increase with the increase of cavity expansion velocity, the ratio of targets radius to comminuted region radius and the lateral confining rigidity.
