EVALUATION OF RIGID-PLASTIC AND ELASTO-PLASTIC MODELS IN SIMULATION OF DEEP-DRAWING PROCESSES FOR SIMPLIFIED AUTOMOTIVE PARTICULAR

The FIAT (Italy) sheet deep-drawing process code for the automotive industry has already been adopted as an Italian benchmark for the evaluation of general purpose simulations. This paper describes a study in which this code was utilized to point out the different responses of two constitutive law models for materials to be formed: the rigid-plastic model and the elasto-plastic model. The two models, as known, involve two different approaches to the whole problem schematization. For the first model, the specialized PLAFOM code and for the secondone, the general purpose ABAQUS code were used. Several calculations were carried out without and with friction effect and the results were compared with experimental data.
