Titre : Springback of a U-draw bending part: study of the geometrical parameters influence on the twisting of the deep-stamped bottom Auteurs : Oualid Kebdani, Bouchaib Radi, Revue : Uncertainties and Reliability of Multiphysical Systems Numéro : Issue 2 Volume : 4 Date : 2021/07/26 DOI : 10.21494/ISTE.OP.2021.0716 ISSN : 2514-569X Résumé : Based on numerical simulations on open curved U-type tools of springback and analysis of these, it was shown that five parameters would have an influence on springback. These five parameters are sheet thickness, die entry radius, punch radius, rolling direction and blank restraint (clamping). The stress delta along the bottom of the draw has a direct impact on the twisting of the draw. Éditeur : ISTE OpenScience
