Abstract

Presented in this paper is a novel idea of applying the elastodynamic reciprocity theorem to guided wave scattering problems. In general, guided wave scattering in solid media involves the mode conversions among a number of modes which make it more complicate than the ones for bulk waves. Consequently, very few analytical solutions have been available while numerical approaches such as FEM and BEM are widely applied. A robust superposition technique based on the use of the elastodynamic reciprocity enables us to obtain guided wave scattering solutions even as closed forms in a much more convenient and efficient manner over conventional approaches such as the integral transform technique. Surface wave interaction with surface a corrosion pit is illustrated to show a generality of the present concept. It is expected that the present approach can be used to establish the measurement models of guided wave for POD analysis and NDE scheme optimization.
