要約(英語): Stress measurements are required to prevent collapse accidents of structures. Surface SH-wave acoustoelasticity can measure principal stress difference non-destructively and easily. Currently, surface SH-wave acoustoelasticity can measure with high precision using a T-type surface SH-wave sensor in ideal environments such as in the laboratory. However, in actual environments, it can not be measured with high precision due to change in the temperature of the specimen. In this paper, temperature dependence of surface SH-wave acoustoelastic constants was verified to investigate the influence of specimen temperature on surface SH-wave acoustoelasticity. In addition, the measuring system of surface SH-wave acoustoelasticity using a cross T-type surface SH-wave sensor to reduce influence of specimen temperature was developed.
