The propagation of elastic waves through a textured granular material
Many metals which have been worked in some way, e.g. forcing or welding, exhibit a textured structure in which the grains may on average be elongated in a particular direction or there may be a preferred crystallographic orientation, or both. In this case the bulk metal will no longer be isotropic, and the results of \textit{I. M. Lifshitz} and \textit{G. D. Parkhomovski} [(*) Zh. Eksp. Teor. Fiz. 20, 175 ff. (1950)] will not apply. In this paper we show how the approach used by Lifshitz and Parkhomovski (*) may be modified to tackle such problems. General results for the attenuation are presented in terms of averages over the particular distribution of orientations. Detailed results are presented for a particular distribution which is a representation of austenitic weld metal.
