摘 要：Harmonic nonlinear ultrasound can offer high sensitivity for residual stress measurements;however,it cannot be used for local stress measurements at a point in space and exhibits nonlinear distortions in the experimental *** paper presents a feasibility study on the measurement of residual stress in a metal plate using a nonlinear Lamb wave-mixing *** resonant conditions for two Lamb waves to generate a mixing frequency wave are obtained via theoretical *** element simulations are performed to investigate the nonlinear interactions between the two Lamb *** show that two incident A0 waves interact in regions of material nonlinearity and generate a rightward S0 wave at the sum *** stress measurement experiments are conducted on steel plate specimens using the collinear Lamb wave-mixing *** setting different delays for two transmitters,the generated sum-frequency component at different spatial locations is *** results show that the spatial distribution of the amplitude of the sum-frequency component agrees well with the spatial distribution of the residual stress measured using *** proposed collinear Lamb wave-mixing method is effective for measuring the distribution of residual stress in metal plates.
