Abstract
The computer aided development of the levelling technology for flat hot rolled products is the main aim of this work. Accuracy of the numerical simulations is important when they are used to develop a real manufacturing technology. The nonlinear combined hardening model was selected to capture the influence of the Bauschinger effect that plays an important role during low cyclic deformation that is characteristic for levelling. The model identification procedure on the basis of cyclic tension/compression tests combined with inverse analysis is described first. Application of the developed model to design efficient leveller setups is presented in the second part of the paper.
