Study on the influence of the springback on the hole expansion ratio characterization
(Whioce Publishing, 2018)
Material formability has become one of the main problems, together with the springback, when stamping high added-value components for the automotive industry. The pursuit of weight reduction has led to higher strength ...
Sensitivity analysis on an AC600 aluminum skin component
New materials are been introduced on the car body in order to reduce weight and fulfil the international CO2 emission regulations. Among them, the application of aluminum alloys is increasing for skin panels. Even if these ...
U-drawing of Fortiform 1050 third generation steels. Numerical and experimental results
(IOP Publishing Ltd, 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 ...
Numerical simulation of the roll levelling of third generation fortiform 1050 steel using a nonlinear combined hardening material model
Press hardening of alternative materials: conventional high- strength steels
(Springer Nature, 2017)
he increase in strength of new high strength steels(HHS) and advanced high strength steels (AHHS) has led toforming issues, such as high springback, low formability, increase of forming forces and tool wear. These problems ...
Roll levelling semi-analytical model for process optimization
Roll levelling is a primary manufacturing process used to remove residual stresses and imperfections of metal strips in order to make them suitable for subsequent forming operations. In the last years the importance of ...
Numerical simulation of U-Drawing test of Fortiform 1050 steel using different material models
(Elsevier Ltd., 2017)
Steel has been used in vehicles from the automotive industry's inception. Different steel grades are continually being developed in order to satisfy new fuel economy requirements. For example, advanced high ...
On the accurate characterization of the drawbead up-lift forces
(IOP Publishing Ltd., 2018)
The competitiveness of the automotive sector has led to a high demand of accuracy and reduction in lead-time of the deep drawing tool making process. In that regard, the numerical simulation of the deep drawing process has ...
Drawbead uplift force analytical model for deep drawing operations
(IOP Publishing Ltd., 2018)
Drawbead uplift force calculation has been an open issue among the deep drawing tool maker and software developers in the last years. Starting from the original work of Stoughton (1988) many have been the models presented ...
Experimental and numerical analysis of the elastic behaviour of the TRIP 700 steel for springback predictions
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2012)
The demand for lightweight fuel-efficient vehicles and the increasing industrial competitiveness between constructors have motivated the automotive industry to introduce new materials and to reinforce the accuracy of metal ...
