Dynamic stresses and displacements around cylindrical cavities of various shapes, namely, circular, triangular, and square cavities are presented in this paper. Also presented are results for a pair of circular cavities of equal radii and a pair of circular and square cavities. These results are of interest in estimating the effects of corners and multiple scattering on the distribution of dynamic displacements and stresses around cylindrical holes or openings. Since exact analytical solutios are not available in these cases (except for a single circular hole) a numerical technique combining the finite element method (FEM) and the method of eigenfunction expansions is used here.
