A general two-dimensional elastodynamic displacement discontinuity method is used to model a variety of application problems. The plane strain problems are: the elastodynamic motions induced on a cavity by shear slip on a nearby crack; the dynamic response of a backfilled versus a non-backfilled tabular excavation or stope; and the interaction between two inclined stopes and a slipping fault. An antiplane strain problem is also presented, where slip occurs along a crack near the surface of a half plane. These problems indicate the wide potential of this method in investigating elastodynamic effects, especially for crack-like geometries.
