Description

The method of equivalent inclusion, originally developed by Eshelby1,2 was first applied to study dynamic behavior of composite laminates by Wheeler and Mura3 where they neglected the presence of the mass density mismatch. Fu4,5 gave a similar formulation for the problem of a pair of ellipsoidal inhomogeneities embedded in an infinite elastic medium subjected to time-harmonic waves. A complete formulation and presentation of analytic and numerical results for a single ellipsoidal inhomogeneity are subsequently given by Fu6 following his work on the ultrasonic determination of fracture toughness, References (7) and (8). The eigenstrain approach is employed and the eigenstrains are expanded as a geometric series in position vector.

The Transmission/Scattering of Elastic Waves by a Simple Inhomogeneity—A Comparison of Theories
