Consolidation of a poroelastic sphere: Numerical investigations of Cryer's problem
In geomechanics the consolidation of a fluid-saturated soil is of great interest and many theories have been proposed in the recent years. A special case is the consolidation problem in a porous, fluid-saturated sphere under drainage and hydrostatic pressure. For this configuration Cryer [2] discussed the special effect of pore pressure response. We increase the complexity of the classical approach, taking into account a modified sphere with an undrained layer. This modification is an expansion of the original problem towards more realistic situations of a poroelastic rock which contains a heterogeneity (modified Cryer problem). It results in nearly effective drainage for the heterogeneity and significant differences in momentary stress state. The interaction between the skeleton and the pore fluid of the porous sphere is implemented numerically with Biot's theory of linear consolidation in an us-p-formulation.
