Non Smooth Fracture Dynamics (NSFD)

We present in this work a modeling approach and an associated numerical strategy both devoted to complex mechanical surface interactions. This approach together with the dedicated numerical strategy are referred as Non Smooth Fracture Dynamics (NSFD). From an applied point of view, this work concerns the comprehension, the prediction and the numerical simulation of dynamic fracture for a wide variety of materials and structures. The main contribution is the ability to predict an entire fracture process: crack initiation, growth, propagation of microcracks, coalescence, propagation of a microcrack, final rupture and post fracture behavior (e.g. frictional contact between created fragments after fracture).
