An Evaluation of Finite Element Models for Soil Consolidation.
Abstract
Numerical performance of Ghaboussi's isoparametric bilinear quadrilateral element, for analysis of quasi-static flow of an incompressible fluid through a linear elastic saturated porous soil, is compared with that of Sandhu's composite element in which the displacement has biquadratic interpolation. Application of both procedures to solution of one-dimensional consolidation and plain strain consolidation of the half-space under a strip load shows that Ghaboussi and Wilson's procedure gives results almost identical to those from the higher order element but is significantly more economical to use.
