Description: An elasto-plastic model has been developed for cohe sive soils which reflects both the elastic and plastic stress-strain behaviour of soils. Two yield surfaces were used to calculate the plastic strain underhydrostaticcompressionand plastic shear strain associated withthefailuresurface. Themodelshowed a goodpredic tion accuracy underboth uniaxialand hydrostatic compressions. Keywords: soil stress-strain, elasto-plastic model, constitutive model, finite element method
