Research of rayleigh surface wave nondestructive measurement for plane residual stresses within a heat-patching disk

In this paper, a nondestructive measurement method of plane residual stress using Rayleigh surface wave and a Rayleigh surface wave instrument for residual stress measurement are described.The paper also describes the Rayleigh surface wave experiment of plane residual stress field within a heat-patching disk by this method. The experiment shows that the measurement results are in good agreement with theoretical results.
