A two-phase coupled elastoplastic-damage model proposed by Ortiz (Ortiz M. Mechanics of Materials 1985;4:67± 93) for modeling inelastic behavior of concrete is considered. For integration of anisotropic damage evolution equations an implicit integration scheme is proposed and the resulting nonlinear
