“…Ultrasonic method [5] turns out to be a good one [6][7]: it is nondestructive, inexpensive and easy to perform. Ultrasonic velocity will change linearly with the stress based on the elastic constants, but the acoustoelastic effect is not that sensitive, time of flight (TOF) should accurate to nanoseconds to acquire the stress change [8].…”

“…So increasing the TOF's sensitivity to stress is very important. In this paper the relationships between velocity and frequency are studied experimentally [6] for different Lamb modes, under various stress loadings. The result shows that the sensitivity of different modes various a lot, the A1 mode is the most sensitivity, compared to S0, S1 and A0 modes; if the force is added to 100 MPa, the change stress of A1 mode can be as large to 80 m/s, which is about 10 times more sensitive than the traditional bulk wave.…”

Abstract. Many factors can cause residual stresses in industry, like rolling, welding and coating. Residual stresses can have both benefits and shortcomings on components, so it is important to find the residual stresses out and enhance its benefits part and get rid of its harmful part. There are many methods for residual stresses detection and ultrasonic method turns out to be a good one for it is nondestructive, relative cheap and portable. The critically refracted longitudinal (LCR) wave is widely used for it is regarded most sensitive to stress and less sensitive to texture which can influence detection results. Ultrasonic methods for residual stresses detection are based on time of flight (TOF) measurement, but because the measurement should reach nanosecond to show stress change, there are many other factors that can influence TOF, like temperature, texture of the components and even the thickness of the couplant. So increasing the TOF's sensitivity to stress is very important. In this paper the relationships between velocity and frequency are studied experimentally [6] for different Lamb modes, under various stress loadings. The result shows that the sensitivity of different modes various a lot, the A1 mode is the most sensitivity, compared to S0, S1 and A0 modes; if the force is added to 100 MPa, the change stress of A1 mode can be as large to 80 m/s, which is about 10 times more sensitive than the traditional bulk wave. This makes it as a good choice for residual stress detection.

“…For example, noncontact acoustic microscopy was applied to measure acoustoelastic constants and residual stresses via surface waves [6]. Duquennoy et al [7,8] derived theoretical formulae to calculate surface wave acoustoelastic constants directly from 2 nd and 3 rd order elastic constants measured using bulk waves. Junge et al [9] introduced a method to recover stresses from the polarization of surface waves instead of wave speed changes because polarization is more sensitive to applied stresses than relative phase velocities.…”

This document contains ABSTRACTSpatially distributed arrays of piezoelectric discs are being applied to monitor the integrity of critical metallic structures using guided elastic waves. These transducers are subjected to in situ operational and environmental conditions, and stress variations are of particular importance because of their cumulative effects on the fatigue life of the structures. Waves propagating between array elements are directly affected by applied loads because of both dimensional changes and the acoustoelastic effect. In particular, changes in phase velocity are a function of the direction of propagation for a particular Lamb wave mode and frequency. This paper shows from numerical solutions of the acoustoelastic wave equation that it is possible to decouple the effects of a homogeneous biaxial stress into its two principal components. As a consequence of this decoupling combined with material isotropy, the acoustoelastic response of guided waves is described by only two constants, both of which can be determined from a single uniaxial loading experiment.
