Abstract
Creation of a robust numerical model of the low cyclic plastic deformation is essential for predicting inhomogeneities occurring during strain path change. Application of such model to simulate various simple plastometric tests (three point bending or tension/compression) is the main subject of the present work. To take this effect into account, a nonlinear isotropic/kinematic hardening material model is considered and all the results are compared with those obtained for the conventional isotropic hardening model. Observed differences in strain and stress distribution are discussed in details. Finally, based on this analysis, conclusions regarding the possibility to apply investigated tests in identification of the material model parameters through the inverse analysis are drawn.
