摘要：

General electromechanical reciprocity relations are applied to the calculation of elastic wave scattering coefficients observed at the electrical terminals of the transducer used in performing an experiment. Both direct backscatter and two transducer geometries are considered. The general formulation is applicable to anisotropic media, but is applied as an example to Rayleigh wave scattering from a surface-breaking crack on an isotropic substrate. This method of analysis is applicable to both the Born and quasistatic approximations and is valid for bulk, Rayleigh and plate wave transducers using any single transduction mechanism. © 1979.
