Reciprocity and Power Balance for Partially Coupled Interfaces

H039 RECIPROCITY AND POWER BALANCE FOR PARTIALLY COUPLED INTERFACES KEES WAPENAAR EVERT SLOB AND JACOB FOKKEMA Section of Applied Geophysics Centre for Technical Geoscience Delft University of Technology The Netherlands Introduction The interaction of elastodynamic waves with imperfectly coupled interfaces has been investigated by many authors for various situations. Schoenberg [2] introduced the linear slip model for an interface between two elastic media. In this model it is assumed that the particle displacement of an elastic wave at an interface jumps by a finite amount linearly proportional to the stress at the interface. The stress itself is assumed continuous across
