Abstract
The diffraction of elastic waves by three-dimensional cracks of arbitrary cross-section is investigated. Using an earlier method [1] for solving the resulting systems of integral equations, the dependence of the resonance scattering frequencies on the crack shape is analysed. The numerical results indicate that the crack shape has a noticeable effect on the distribution of resonance poles in the complex frequency plane. In theory, this means that the information obtained can be used to solve inverse problems of flaw detection (determining the size and shape of a crack from the reflected signal).
