✦ Synopsis

Generalized plane strain is characterized by geometries of cylinders of ®nite or in®nite length with boundary conditions that do not change in the direction of the generators. The resultant ®eld generally contain three-dimensional stress and strain components, but has only two-dimensional spatial dependency. In addition to the classical plane strain deformation, it admits axial strain, warping, torsion, shear, bending, among other elementary deformation modes. The study of generalized plane strain solutions has so far been limited to elasticity. The present paper seeks the parallel development for poroelasticity. Due to the mathematical diculty arising from the coupled nature of poroelasticity, analyses here are restricted to materials with orthotropic properties and cylindrical geometries whose longitudinal axis coincides with one of the material principal axes.
