Seismic Radiation from a Kink on an Antiplane Fault

  title={Seismic Radiation from a Kink on an Antiplane Fault},
  author={Mokhtar Adda-Bedia and Ra{\'u}l Madariaga},
We study radiation and energy balance for an antiplane fault containing a kink. A semi-infinite crack with a sharp rupture front propagates along the flat portion of a kinked crack. At time t 0, the crack reaches the kink located at the origin of coordinates and continues propagating beyond the kink at a different speed. We compute the exact solution for this problem using a Chaplygin transformation, a variation of the well-known Cagniard–de Hoop method. We first establish an integral equation… CONTINUE READING
