Return mapping algorithm for an enhanced generalized plasticity constitutive model of partially saturated soils

The objective of this paper is to investigate the stress update algorithm and the tangent operator for an enhanced generalized plasticity model developed recently for partially saturated soils, where on top of the hydrostatic and deviatoric components of the (effective) stress tensor suction has to...
