00925njm 22002777a 4500 dc GALDOS, Lander author Sáenz de Argandoña, Eneko author Mendiguren, Joseba author Silvestre Soriano, Elena author 2017 Elasto–plastic behavior of the third generation Fortiform 1050 steel has been analysed using cyclic tension–compression tests. At the same time, the pseudo elastic modulus evolution with plastic strain was analysed using cyclic loading and unloading tests. From the experiments, it was found that the cyclic behavior of the steel is strongly kinematic and elastic modulus decrease with plastic strain is relevant for numerical modelling. In order to numerically analyse a U-Drawing process, strip drawing tests have been carried out at different contact pressures and Filzek model has been used to fit the experimental data and implement a pressure dependent friction law in Autoform software. Finally, numerical predictions of springback have been compared with the experimentally ones obtained using a sensorized UDrawing tooling. Different material and contact models have been examined and most influencing parameters have been identified to model the forming of these new steels. 1742-6588 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=145968 https://hdl.handle.net/20.500.11984/1110 Numerical simulation of the roll levelling of third generation fortiform 1050 steel using a nonlinear combined hardening material model
