The dynamic response of axisymmetric poroelastic bone subjected to transient pressure along the curved surface of the cylinder is studied. In the analysis, exact solutions that satisfy the boundary conditions are obtained by applying Laplace transformations to the equations of motion and fluid flow. The Laplace inversion is obtained from the residue theorem. The stress component (sigma)[inf rr][sup *] (dimensionless) is plotted with T (dimensionless time) for various (eta)[sup *] (dimensionless decaying parameter). It is seen that the stresses behave alike for different (eta)[sup *]. In the region 1
