Material behavior simulation of 42CrMo4 steel

It is becoming increasingly important to make possible constitutive modelling and simulation of material behaviour for the prediction of possible failures in material. This can allow to the optimization of design of highly loaded engineering components. In order to achieve that goal, material parameters should be accurately determined for the chosen material model. The major step in material parameters identification is material behaviour simulation. The procedure of material behaviour simulation is based on the results of the fatigue testing on the materials' samples. The paper presents the procedures required for the material behaviour simulation of 42CrMo4 steel, starting from the fatigue testing, through numerical procedures related to complex material model, which results in material parameters identification, to the validation of described procedures by comparison of the simulated and real materials response in cyclic loading conditions.
