00925njm 22002777a 4500 dc Mendiguren, Joseba author Gomez-Mitxelena, Xabier author GALDOS, Lander author 2015 The elastic behaviour of TRIP 700 steel under plastic deformation is analysed. The analysis is carried out by means of classical tensile test and loading–unloading cyclic tests. These tests have been performed using high deformation strain gages, which enable an accurate and continuous measurement of strain. An elastic modulus reduction of 20% is observed for 12% plastic deformation. Furthermore, non-linear unloading and loading paths have been found in this work. This is an important difference with respect to other authors and opens new possibilities for the development of new material models to improve the prediction of the post-forming springback of industrial parts, which is an important issue for the automotive industry. 0921-5093 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=109640 https://hdl.handle.net/20.500.11984/5363 springback TRIP 700 Elastic unloading Non-linear elastic loading Inelasticity Pseudo-young modulus Elastic behaviour characterisation of TRIP 700 steel by means of loading-unloading tests
