Summary

 The evaluation of material parameters for viscoplastic Chaboche and Bodner-Partom formulations is carried out using tensile tests only. The determination of the Bodner-Partom law is quite easy. The parameter study for the Chaboche law usually requires carrying out strain-controlled cyclic tests. In this work, we propose supporting this type of experiments by numerical simulations. A set of parameters for each formulation is identified for steel, and is used to calculate the dynamic behaviour of circular plates. The results are compared with the experimental data on steel plates.

Key words Identification, viscoplasticity, dynamics, circular plate, tensile test, cyclic loading
