This paper presents a three-dimensional consolidation model, based on mixture theory. Both the Eulerian and the Lagrangian formulations are given in one dimension for finite strain and general material nonlinearity. Then the paper formulates the initial boundary value problems related to several situations of relevant geotechnical engineering interest, such as consolidation between draining and impervious boundaries subjected to stress and/or velocity conditions, consolidation under own weight of a layer growing due to deposition of wet material, or to sedimentation of solid particles in a quiescent fluid.

    • "Speciÿcally, the following topics, among several ones, are indicated: (i) The consolidation models proposed in this paper have been derived, for the one-dimensional case. The whole modelling procedure should be revisited in the three-dimensional case exploiting again, the general framework proposed by Lancellotta and Preziosi [12], mixtures theory [21], and recent studies on the modelling of Darcy's phenomenon [22] for the proper closure of the balance equation. (ii) The relevance of material non-linearity can be described in a relatively more careful way if smallness assumptions on the strain is removed. "

    ABSTRACT: This paper deals with the modelling of non-linear consolidation phenomena in a non-homogenous clay characterized by soil properties with change of type going from normal to over consolidation regimes. Some simulations are developed addressed to visualize the main features of the consolidation process. A critical analysis, which gives special attention to research perspectives, concludes this paper.

    ABSTRACT: This paper deals with the derivation of a finite deformation model in the Lagrangian formulation framework without introducing any a priori partition of the stress tensor between the fluid and the solid skeleton.

    ABSTRACT: This paper reports about the derivation of a fully nonlinear model characterized by finite deformations without smallness assumptions. The soil is assumed to be saturated, and no restrictions are introduced on the constitutive laws. Initial boundary value problems are formulated with reference to geotechnical problems, such as consolidation under own weight or sedimentation of solid particles in a quiescent fluid, and back-analyses of field performance of an embankment resting on a soft clay deposit.
