Tensile Fracture Simulation in Rock Using Augmented Virtual Internal Bond Method
The augmented virtual internal bond (AVIB) method is a newly-developed micro constitutive model. The micro fracture mechanism is implicitly incorporated into the constitutive relation through the micro bond potential. Therefore, it does not need any macro fracture criterion in simulating fracture propagation, which is highly efficient in fracture simulation. In this paper, the AVIB is embedded into the commercial finite element software ABAQUS and used to simulate tensile fracture propagation in rock. By comparing the numerical results with existing experiments, it is indicated that the AVIB is an efficient method to simulate fracture propagation in rock. With the AVIB being implemented into ABAQUS, it is believed that the AVIB provides an efficient approach to rock failure analysis.
