Abstract In this paper, axial symmetric wave in a double porosity semi-infinite bore containing fluid is investigated in two cases. In the first case, empty bore is considered, and in the second case, bore containing fluid is considered. In the former case, internal lateral surface is assumed to be stress free, and in the latter case, continuity of stresses and displacements are imposed. In either case, phase velocity is computed as a function of an aspect ratio, and the numerical results are presented graphically.
