Abstract

The aim of this note is to study the effect of negative Poisson's ratio on the quasi-static deformation of a poroelastic half-space with anisotropic permeability and compressible fluid and solid constituents by surface loads. Two particular cases considered are: two-dimensional normal strip loading and axisymmetric normal disc loading. It is found that a negative Poisson's ratio makes the Mandel-Cryer effect more prominent. It also results in an increase in the magnitude of the surface settlement.
