Abstract
Based on the theory of multiple displacement fields, the quasi-static MPM has been extended to simulate crack behavior in this paper. Compared with the existing crack simulation methods, this new method not only avoids the meshing difficulties and complex shape functions but also supports the modeling of crack growth in an arbitrary direction. The key fracture parameters, stress intensity factors, are calculated by the interaction integral method and proved accurate through the example of a cracked plate under uniaxial tension. The crack propagation is predicted with the maximum circumferential stress criterion and applied in the simulation of a compact tension test of clay. Based on this study, the proposed method is suggested as an effective scheme for modeling soil crack behaviors that are not limited to small deformation.
