## Abstract

An extension of M. A. Biot's theory into the nonlinear anelastic range is presented in the paper. The resulting coupled field equations obtained by viewing soil as a multiphase medium consisting of an anelastic porous skeleton and viscous fluids, and the modern theories of mixtures are combined. In order to relate the changes in effective stresses carried by the soil skeleton to the skeleton rate of deformations, a general analytical model which describes the nonlinear, anisotropic, elastoplastic, stress and strain dependent, stress-strain-strength properties of the soil skeleton when subjected to complicated three-dimensional, and in particular to cyclic loading paths, is used. A brief summary of the model's basic principle is included and the constitutive equations are provided. The use of the proposed formulation for solving boundary value problems of interest in soil mechanics is illustrated.
