On hardening anisotropy of <i>K</i>₀‐consolidated clays

Abstract

Abstract The combined isotropic‐kinematic hardening rule for clays is presented using the concept of a multisurface model discussed previously in Reference 1. The mechanical behaviour of clays after one‐dimensional consolidation is next simulated for the axisymmetric stress stress state. A general three‐dimensional formulation of constitutive relations is also presented.
