The scattering of ultrasonic waves in polycrystalline materials with texture

摘要: The theory of ultrasonic propagation in polycrystals with independent and uniformly distributed orientations the grains presented previous papers [J. Acoust. Soc. Am. 72, 1021–1031 (1982); 73, 1160–1163 (1983)] is generalized to calculate scattering coefficients phase group velocities plane compressional shear waves textured polycrystals. calculation was done for cubic symmetry rolling texture second‐order perturbation using assumption that changes material constants from grain are small. In limit equal zero analytical results exactly same as those untextured previously presented. Numerical calculations carried out some examples.
