| Abstract: | The method based on the stress-ultrasonic velocity relation has been appliedto axial stress measurements in bolts. But the ultrasonic velocity is dependent on manymaterials parameters, such as elastic modulus, density and temperature. So it is impor-tant to realize how the ultrasonic velocity varies with stress and temperature in differentmaterials. In this paper, experimental and calculating approaches for the analysis of ul-trasonic velocity-stress-temperature relation are described, and results for three metallicmaterials are also given. |
