摘要：

Investigation of the correlation between measure of damage tensor and acoustic anisotropy of specimens from commercial alloy was carried out. The relationship between the principal values of damage tensor and the velocities of ultrasonic waves was established. The formula for acoustic anisotropy based on the principal values of damage tensor was proposed. It allows to describe the anisotropy of the accumulation of damages, which have a significant influence on acoustic anisotropy. The nonlinear dependence of acoustic anisotropy on local deformations and axial stresses in the region of large plastic deformations was observed. The results of the investigation indicate the possibility of estimating of damage based on measurements of acoustic anisotropy. It has a great importance for an objective estimating the state of engineering structures by acoustic methods. Copyright (C) 2017 The Authors. Published by Elsevier B.V.
