Rayleigh Wave Measurement of Surface Stresses in Stainless Steel Piping
- 129 Downloads
The acoustoelastic effect for surface waves is used to measure the residual stress field on the inside and outside surfaces of a stainless steel pipe, near a circumferential weld. Rayleigh waves are launched on the pipe with electromagnetic transducers. An in-situ calibration technique is used to calculate the proportionality coefficients between stress and variation of velocity of the Rayleigh wave. The stress profiles obtained are compared with theoretical and experimental results published by other authors.
