Abstract

This paper is mainly based on the basic principle of the extended finite element ,in the large commercial software abaqus on the platform of dynamic load eccentric mixed-mode of concrete failure process are numerically simulated, the results showed that the crack together under tension and shear ,crack extension direction and the direction of cracks was obvious deflection, and is in good agreement with the physical experiments, also shows that the extended finite element fracture problems have very good advantage.
