Transient elastic waves applied to nondestructive testing of transversely isotropic lossless materials: a coordinate-free approach

Transient plane wave theory for anisotropic, in particular transversely isotropic lossless materials is formulated and evaluated as a coordinate-free approach leading to comparatively simple analytical expressions for phase wave speeds, polarization vectors and energy wave speeds. The application to the practical problem of nondestructive testing of dissimilar welds yields a concise physical interpretation of the output of numerical simulation codes.
