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 ...
Roll levelling semi-analytical model for process optimization
(IOP, 2016)
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 ...
Sensitivity analysis on an AC600 aluminum skin component
(IOP, 2016)
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 ...
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 ...
Towards the automation of the die spotting process: Contact blue pattern decryption
(Elsevier Ltd., 2020)
Automotive die spotting is one of the most complex and least standardized processes in the tool making process. A spotting expert identifies local contact areas through a blue-paste pattern and the die/sheet contact is ...
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 ...
The Interaction between the Sheet/Tool Surface Texture and the Friction/Galling Behaviour on Aluminium Deep Drawing Operations
(MDPI, 2021)
The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges ...
Comparison of the hardening behaviour of different steel families : from mild and stainless steel to advanced high strength steels
(Elsevier Ltd., 2015)
Although steel has been used in vehicles from the automotive industry's inception, different steel gradesare continually being developed in order to satisfy new fuel economy requirements. For example,advanced high strength ...
Influence of the pressure dependent coefficient of friction on deep drawing springback predictions
(Elsevier Ltd., 2016)
The aim of this work is to show the influence of defining a pressure dependent friction coefficient onnumerical springback predictions of a DX54D mild steel, a HSLA380 and a DP780 high strength steel. Thepressure dependent ...
Elastic behaviour characterisation of TRIP 700 steel by means of loading-unloading tests
(Elsevier Ltd., 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 ...
