The constitutive equation of friction has been developed by the authors so as to describe the smooth transition from the elastic to plastic sliding state and the transition from the static to the kinetic friction and its vice versa, which is called the time-dependent subloading-friction model. In this article this model is further extended so as to describe the anisotropic hardening by incorporating the concept of the rotation of yield surface, i. e. the rotational hardening that has been adopted in the elastoplasticonstitutive equation of soils.
