Models for the Frequency Dependence of Ultrasonic Scattering from Real Flaws.
Abstract
Scattering of elastic waves at flaws embedded in titanium was analyzed by measuring frequency and angular dependence of the scattered intensity pattern. This scattered intensity pattern was also calculated from two existing theories: (1) Keller's geometrical theory of diffraction, which was solved for two-dimensional, crack-life flaws of circular and elliptical symmetries; (2) Born approximation, a scattering theory (introduced by Krumhansl et al., Cornell) for the spherical oblate and prolate spheroidal cavities. The experimental result was favorable compared to theory.
