Abstract:SUMMARYA constitutive operator split method with implicit-explicit time integration is presented for the transient analysis of rigid block models of jointed media. The linear portion of the joint constitutive law is integrated by an implicit method and the non-linear, time dependent portion is integrated by an explicit method. The method features the stability of implicit procedures as well as the flexibility of explicit procedures for non-linear problems. The solutions obtained with this method are compared t… Show more
