In this work, the dynamic interaction between defects of different types such as cracks and
cavities in a smoothly inhomogeneous, elastic anisotropic plane subjected to incident SH-
waves is investigated. Solution of the ensuing boundary-value problem is numerically
realized using the non-hypersingular, traction boundary element method (BEM). By
employing a special functional transform, the wave equation for inhomogeneous media is
reduced to one with constant coefficients and the relevant frequency-dependent …
