Abstract

Propagation of plane elastic waves in materials with cavities of various shapes and cracks (or mixtures of cavities of diverse shapes) is discussed in the longwave limit. In this limit, the wavespeeds are determined by the effective elastostatic moduli, i.e. the material is modeled by the homogeneous elastic solid having effective elastic constants.
