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 ...
The influence of the kinematic hardening on the FEM simulation of Tension Levelling Process
(Elsevier Ltd., 2020)
Tension levelling is used in the steel industry to remove shape defects present in cold rolled strip. This technology is increasingly being employed by steel makers to level AHSS steels, because conventional roll levelers ...
Simulation of Cold Forging Processes Using a Mixed Isotropic-Kinematik Hardening Model
(Springer, 2021)
Cold forging is a manufacturing process where a bar stock is inserted into a die and squeezed with a second closed die. It is one of the most widely used chipless forming processes, often requiring no machining or additional ...
Numerical study of advanced friction modelling for sheet metal forming: influence of the die local roughness
(Elsevier Ltd., 2022)
Numerical simulation of sheet metal forming processes has become indispensable in the last decades. Although the complexity of the frictional behaviour is identified as a key factor for the prediction accuracy, the industry ...
Contact pressure, sliding velocity and viscosity dependent friction behavior of lubricants used in tube hydroforming processes
(2021)
The final quality of sheet and tube metal formed components strongly depends of the tribology and friction conditions between the tools and the material to be formed. Furthermore, it has been recently demonstrated that ...
Post-forming, electro-plastic effect internal stress reduction in AA5754 aluminium alloy
(Elsevier, 2022)
Aluminium alloys are one of the most efficient materials for weight reduction in the car industry. However, the favourable performance of alloys conflicts with the difficulties of transforming these materials through plastic ...
AA5754 aluminium alloy springback reduction by post forming electro plastic effect (PFEPE)
(Elsevier, 2024)
Post Forming Electro Plastic Effect (PFEPE) has been proposed as a promising technology for mitigating forming forces and addressing springback challenges in the metal forming industry. However, several research gaps remain ...
