ON THE DYNAMICAL PROCESS OF FAULT MOTION IN THE PRESENCE OF FRICTION AND INHOMOGENEOUS INITIAL STRESS PART I. RUPTURE PROPAGATION

摘要: An equation which represents the crack propagation is obtained by approximating wave and boundary conditions in neighborhood of dislocation surface. The problem with an unsteady finite rupture velocity solved aid this model computation carried out using difference method. proposed takes as diffusive phenomena inhomogeneous initial stress field. It clarified paper that most important focal parameters for dynamical process fault motion are effective (defined static frictional minus sliding stress) fracture strength stress). former accelerates latter decelerates it. All can be interpreted relative magnitude between these stresses. importance both stresses not ascertained until field introduced.
