A smooth particle dynamics method considering material point failure for crack propagation simulation applied in rock mechanics

Abstract: The numerical simulation of rock fracture mechanics has been a major research hotspot and challenging area in the field of rock mechanics. Based on this background, a smooth particle dynamics numerical simulation method (RGIMP) is proposed to consider the failed material point. The RGIMP algorithm is simple in form, does not need to use multiple velocity fields, takes advantage of the efficient computational efficiency and stability of the GIMP itself, and simulates the brittle fracture process of the rock by … Show more
