On “fundamental solutions for a fluid-saturated porous solid” by M. P. Cleary

Abstract

This note corrects expressions given by Cleary [1] for fluid mass source and dipole solutions in linear fluid infiltrated porous elastic solids. The corrected expressions reveal that the stress and displacement fields due to a suddenly applied point force comprise a time independent portion that is the classical elasticity solution based on the undrained (short-time) moduli, and a time dependent portion that is the solution for a continuous fluid mass dipole. As a corollary, the time dependent functions entering the point force solution can be obtained from a single function that enters the solution for displacements due to a fluid mass source.
