Investigation of ultrasonic methods for residual stress measurement
Three ultrasonic methods were investigated for nondestructively measuring residual stress in metals. Shear wave birefringence using a multiarticulated sample positioner and motorized transducer rotator was found to be very sensitive, but the results strongly depend on the matrial texture. Rayleigh wave measurements using a corner reflector and motorized goniometer have marginal sensitivity, but alternate methods using wedge, knife edge, or needle point contacts have sensitivity comparable to shear wave birefringence. The use of wave-propagation coefficients in conjunction with combinations of measurement methods appears to be at least as promising a technique as use of shear horizontal waves and promises to require much smaller transducers. 80 refs., 10 figs.
