Description

In order to make a fracture mechanical prediction of the remaining lifetime of a part, it is necessary to know the overall size, shape and orientation of the flaws in the part. This paper describes the determination of these flaw characteristics from measurements of the scattering of low frequency (long wavelength) ultrasound from the flaw. Experimental results are excellent.
