analytical and experimental work are presented on the problem of wave propagation reflection and refraction phenomena occurring in isotropic and anisotropic materials as well as at their boundaries. results of wave behaviors at isotropic-anisotropic as well as anisotropic-anisotropic boundaries are given. the samples considered are single crystals bonded to polycrystals as well as single crystals bonded together (using diffusion-bonding processing) with different axes or orientation. the objective of this investigation ...
ultrasonic waves have been used as a valuable tool to determine material properties in homogeneous isotropic materials. real materials, such as welds and castings, however, due to heat treatment, may become anisotropic as well a inhomogeneous. such additional complexities will alter the wave propagation resulting in losses due to single and multiple scattering, mode conversion, etc. earlier work by kupperman et al. and simpson et al. is of particular interest ...
