### Abstract

Fully coupled analysis of a narrow poroelastic beam subjected to constant deflection and biaxial flow has proved intractable, but an approximate uncoupled solution does exist. Finite element analysis of this problem shows that the uncoupled approximation is quite accurate with respect to reaction force, pore pressure and strains. As the width-to-thickness ratio of the beam increases, the error in the analytical solution increases, because it does not allow for bending in the transverse plane. This could be included by using plate theory to enhance the accuracy of the uncoupled solution, but the result would remain approximate, and the errors in the simpler solution are small enough that the extra complication would rarely be justified.
