Abstract

The topic of this presentation is the numerical analysis of saturated soil by the finite element method. As the solution procedure should be extended to describe the flow of the pore fluid through the deforming solid skeleton, a time dependency is introduced into the problem. Therefore, the time coordinate has to be discretized and treated by an appropriate integration scheme. In contrast to adaptive mesh refinement strategies in the spatial domain which are well founded for elasticity and have also been successfully applied to elastic-plastic problems only few papers deal with time adaptive procedures for the quasi-static analysis of consolidation.
