In this study, the static deformation of a fault system under constant stress drop is determined through the zero frequency approximation from a corresponding dynamic crack problem. The corresponding dynamic crack problem is formulated and solved by hypersingular boundary integral equation method(HBIEM). The relative displacement of the crack surface as well as the dynamic stress intensity factor of the crack tips can be calculated. Some numerical results are presented and possible implications in geophysics and earthquake engineering are also addressed. |
