摘要：

We extend the work of a previous paper to give a long-wavelength approximation for elastic wave scattering by an elliptical flat crack. Explicit formulas for the far-field scattered amplitudes in this approximation are given for various experimental configurations. These formulas are then applied to give a simple inversion procedure. The orientation and eccentricity of the crack are readily determined from unnormalized scattering data. The size may be determined from an absolute intensity measurement.
