• Theoretical modeling of acoustoelastic effects in plastically deformed solids has been accomplished through the use of an elastoplastic coupling strain rate. This coupling strain rate, which remains effective even under subsequent elastic loading, is considered to be generated at the yield surface vertex and causes elastic modulus degradation due to the growth of plastic anisotropy. The purpose of the present paper is to formulate precisely a generalized acoustoelastic theory for plastically deformed solids with finite deformation, and moreover, to provide a method of nondestructive evaluation of the plastically deformed state, i.e., yield surface, texture change due to the plastic deformation and the occurrence of the instability associated with the microslip band.
