Woznica, K.; Kłosowski, P. Evaluation of viscoplastic parameters and its application for dynamic behaviour of plates. (English) Zbl 0985.74011 Arch. Appl. Mech. 70, No. 8-9, 561-570 (2000). Summary: Using tensile tests only, we evaluate material parameters for viscoplastic Chaboche and Bodner-Partom models. The determination of Bodner-Partom law is quite easy. The parameter study for Chaboche law usually requires carrying out strain-controlled cyclic tests. In this work, we confirm 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 experimental data on steel plates.
