N2 - Residual stress has significant impacts on the performance of the mechanical components, especially on its strength, fatigue life, corrosion resistance, and dimensional stability. In this chapter, based on acoustoelasticity theory, the ultrasonic linear detection method of residual stress and the nonlinear detection method are analyzed in theory. In the study of ultrasonic linear detection method, the time of longitudinal wave propagation along the stress direction and shear wave with a propagation direction perpendicular to the stress direction and a polarization direction parallel to the stress direction are used to characterize the stress value. In the study of ultrasonic nonlinear detection method, ultrasonic nonlinear coefficient of second order and third order is used to characterize the stress. To build experimental systems to contrast the detection results of linear method and nonlinear method, it shows that the two methods have good agreement. At last, the linear and nonlinear method are applied to field detection of residual stress, and achieved good results.
