In this paper, the continuum damage mechanics (CDM) model formulation proposed by [Eng. Fract. Mech. 58(1/2) (1997) 11] has been validated against ductile damage evolution experimentally measured in A533B low alloy steel under various stress triaxiality conditions. A procedure to identify the model parameters has been defined first. Then, the model has been used to simulate, via finite element analysis (FEA), tests on notched flat rectangular bars with different notch radii. The experiments and the FEA predictions are finally compared with each other. The results presented here confirm the transferability of damage parameters definition and the potential of the proposed damage model in predicting ductile failure occurrence in structures and components under multi-axial state of stress loading conditions.
