Numerical Simulation on the Compound Crack Propagation Process in Concrete

Abstract:

In this paper, numerical simulation on the failure process of the mixed mode crack about the concrete is carried out. The results show that the crack initiation angle and the peak load increase as the distance between the preexisting crack and the midline of the beam is greater, the distance is constant, the longer the length of the preexisting crack is, the bigger the peak load is. Due to the heterogeneity of concrete materials, the crack propagation path is tortuous, and tensile stress is the major driving force.
