Abstract

The subject of this paper is to deal with the possibility of residual stress measurements by ultrasonic technique. The objective of the work is to evaluate the method in the case of biaxial stresses near the external surface. For this purpose, we use surface Rayleigh waves or longitudinal waves parallel to the surface, generated and collected by special dual transducers. We use signal processing to measure to measure delta time of flight. Results obtained on pressure vessels are compared to calibration in the case of uniaxial stresses.
