In the previous paper, the theoretical results of the acousto-elastic effects caused by plastic anisotropy growth were presented. The objective of the work reported in this paper is to present a numerical example of the correlation between the acousto-elastic effects and plastic anisotropy growth. Numerical calculations have been made for a uniaxial tension test of an aluminum by using the third-order elastic constants measured by Crecraft and the anisotropy parameter and a Bauschinger modulus of cold rolled aluminum reported by Svensson. By comparison of both simulation models based on the flow theory and the corner theory with previously reported experimental observations, it is suggested that plastic anisotropy is closely related to the acousto-elastic effects through the vertex-like yield effects of the corner theory.
