| Outline of Final Research Achievements |
We present analytical time-domain expressions for 2D extended boundary integral equation method (XBIEM) kernel functions, which represent the transient displacement and stress responses of an infinite homogeneous isotropic medium to a constant traction applied on a line surface element. Using kernels, we propose an implicit time-stepping scheme to simulate a dynamic rupture crossing a bimaterial interface and show the significant control that medium inhomogeneity exerts on rupture propagation.
