Abstract
Elastic imaging of circular inclusion in 2D elastic medium is considered. Suppose a circular inclusion embedded in a homogeneous, isotropic elastic material. The object is subjected to an arbitrary incident acoustic wave from far-field. The authors use four equations to present elastic imaging method by Kolosov–Muskhelishvili’s analytical solutions. Basing on displacement field derived from analytical solutions, several elastic parameters are computed, including three of nine stress tensors, axial, and shear strain tensors field for imaging. The method is applied to solve imaging problems by elastic mechanical properties. Experiments show the reconstruction shear modules distribution simply derived from shear stress and strain tensors field presents a good agreement with the given value, which illustrates the effectiveness of the method.
