A poroelastic material can imbibe solvent and swell. When the material swells inhomogeneously or
swells under external constraints, stresses can develop inside the material. The stresses can trigger
mechanical instabilities in the material or even break the material, which have been often observed
in experiments. In this paper, we study the wrinkling instability of a circular poroelastic plate, in
the process of solvent molecules migrating into the plate from the edge. The critical conditions for
the initiation and disappearance of wrinkles in the plate are presented.
