The new potential proposed in [1] is used to modify Concrete Damaged Plasticity [2] model. The formulas for plastic multiplier and elastoplastic stiffness tensor are derived and simple numerical test are performed to confirm validity of the change. Predictions of the modified model and the original model are compared. The comparison shows similar character of the resultant curves, although for some cases a distinct quantitative difference between the models is revealed.
