This paper deals with damage induced anisotropy modelling for concrete-like materials. A thermodynamics based constitutive relationship is presented coupling anisotropic damage and elasticity. The biaxial behaviour of such a model is analysed through the effects of yield surface modifications by the introduction of new equivalent strains.
