Abstract

A microplane model for the inelastic behavior of soils is presented. The microscopic constitutive equations are defined independentely for a set of microplanes covering all possible orientations, with a kinematic micro-macro constraint. The stresses on each microplane are defined as explicit functions of the volumetric and deviatoric normal and shear components of the macroscopic strain tensor. The model can reproduce drained as well as undrained behavior, with an uncoupled formulation between the stress-strain and the pore water pressure terms. The model is calibrated and verified. The model involves nine material parameters but four can be fixed constant and five have to be determined by data fitting.
