摘要
Disclosed is a method for evaluating the structural integrity of an object, including the steps of generating a lowest order horizontal shear wave in the object, detecting the wave after it has propagated through the object, time gating the detected signal to reject nonuseful portions, Fourier transforming the time response of the detected signal into a frequency dependent response, and predicting the structural integrity of the object from the characteristics of the frequency response.
