Description

Because they propagate through the plate without losses arising from mode conversion and are scattered by heterogeneities without mode conversion, SH-waves are theoretically well suited for inspection of cracks or discontinuities in the material properties and do not depend on the out-of-sagittal plane coordinate. The scattering of time harmonic plane SH-waves by cracks or discontinuities in the material properties of an infinite plate is analytically/numerically investigated. The method is based on a domain decomposition mode-finite element method.
