A strategy for solving the non symmetries arising in nonlinear consolidation of partially saturated soils
The main scope of this paper is to present an alternative to tackle the problem of the non symmetries arising in the solution of the nonlinear couple consolidation problem based on a combination of different stress states. Being originally a non symmetric problem, it may be straightforward reduced...

description 
The main scope of this paper is to present an alternative to tackle the problem of the non symmetries arising in the
solution of the nonlinear couple consolidation problem based on a combination of different stress states. Being originally a non
symmetric problem, it may be straightforward reduced to a symmetric one, and the conditions in which this reduction may be
carried out, are addressed. Non linear saturationsuction and permeabilitysuction functions were regarded. The geometric
model was developed considering an updated lagrangian description with a corotated Kirchhoff stress tensor. This description
leads to a nonsymmetric stiffness matrix and a simple alternative, using a symmetric constitutive matrix, is addressed to
overcome this situation. The whole equation system was solved using an open finite element code FECCUND, developed by
the authors. In order to validate the model, various examples, for which previous solutions are known, were solved. The use of
either a strongly non linear and no symmetric formulation or a simple symmetric formulation with accurate prediction in
deformation and porepressures is extremely dependent on the soil characteristic curves and on the shear efforts level, as well.
A numerical example show the predictive capability of this geometrically non linear fully coupled model for attaining the
proposed goal.
