AN EFFECTIVE STRESS APPROACH TO UNDRAINED ANALYSIS. NUMERICAL MODELS IN GEOMECHANICS. NUMOG III. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM HELD IN NIAGARA FALLS, CANADA, 8-11 MAY 1989
The purpose of this paper is to introduce a finite element formulation for fully undrained analysis in terms of effective stresses. The approach is based on the assumption that the pore pressure is related to the total stresses using henkel's pore pressure parameters. The formulation is generally valid for any type of elasto-plastic material models. An elasto-plastic model is used to analyze the deformation of the expansion of a long cylinder for which the analytical solution is available for comparison. Both elastic perfectly plastic and strain softening models are used in this analysis. A friction model using the Mohr Coulomb criterion is then used to analyze a strip footing to study the generation of pore pressure and the propagation of the failure zone beneath the footing.
