Means for Increasing the Sensitivity of Acoustic Probing when Studying the Structure of Metals

Abstract

As exemplified by the use of different approaches to processing the results of probing metals with elastic waves, means have been studied for increasing the sensitivity of the ultrasonic method. Representing processes that determine the effect that a medium has on the parameters of an elastic wave by a statistical model in the form of a Dirichlet distribution makes it possible to numerically characterize changes in the structure of a probing pulse and to improve the understanding of phenomena that occur when an elastic wave interacts with a medium, with the degree of material damage taken into account.
