查询词典 critical angle

Firstly, by comparing with the corresponding problems in full space, we applied the BIEs to investigate the features of spontaneous rupture on a planar fault in half space for theoretical numerical models, and obtained some significative results on the roles of asperity radius, critical slip-weakening distance, fault depth, dip angle of fault, initial stress distribution and strength distribution in the rupture propagation processes.
