Using an elastodynamic boundary integral formulation coupled with a cohesive model, we study the problem of a dynamic rupture front propagating along an heterogeneous plane. We show that small-scale heterogeneities facilitate the supershear transition of a ...
Along a planar interface bonding two solids made of Homalite, we simulate rupture events in the presence of a unique tougher inclusion with insights on the influence of its geometry and fracture properties. Our study is then pursued with fracture planes ma ...
The onset of rapid slip along initially quiescent frictional interfaces, the process of “earthquake nucleation,” and dissipative spatiotemporal slippage dynamics play important roles in a broad range of physical systems. Here we first show that interfaces ...
Recent experiments reveals how dynamic fracture is characterized by the interplay of crack front with microscopic material heterogeneities. Heterogeneous dynamic fracture remains a current challenge both for numerical modeling and experiments because of th ...
Using a spectral resolution of the elastodynamic boundary integral equations, this poster is presenting the effect of tougher heterogeneities along a planar fracture plane. A centered crack propagating along a 1-D heterogeneous interface under mixed-mode l ...
We investigate numerically the dynamic inplane propagation of a centered crack along bimaterial interfaces using a spectral formulation of the elastodynamic boundary integral equations. Particular attention is given to the effect of contact zones at the su ...
The onset of earthquakes along crustal faults, the triggering of slab avalanches or the break of a wine glass are all serious problems driven by the propagation of a dynamic rupture front. Our physical understanding of this ubiquitous phenomenon is however ...
