New drawbead tester and numerical analysis of drawbeads closure force
(Springer, 2021)
Currently, a great deal of controversy exists regarding the real forces generated in drawbeads during sheet metal forming processes. The present work focuses on the analysis of the uplift force. First, a detailed literature ...
Initiation of dynamic recrystallization of as-cast N08028 alloy
(ESAFORM, 2021)
The use of high nickel content austenitic stainless steels (SASS) has significantly increased in the last decade. The corrosion and high fatigue resistance of these materials make them suitable for manufacturing oil country ...
Hole expansion test of third generation steels
(AIP Publishing, 2017)
The trend towards the implementation of new materials in the chassis of the automobiles is considerably making more complex the manufacturing of the components that built it up. In this scenario materials with higher ...
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 ...
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 ...
Plasticity evolution of an aluminum-magnesium alloy under abrupt strain path changes
(Springer, 2022)
During the forming and manufacturing of engineering materials, plasticity behavior could be evolving significantly due to complex deformation history. Therefore, this study aims to characterize the plasticity evolution of ...
In-situ analysis of the elastic-plastic characteristics of high strength dual-phase steel
(Elsevier, 2022)
Modeling the elastic behavior of dual-phase steels is complex due to the strain dependency of Young's modulus and high elastic nonlinearity. Since it is assumed that reasons for this are to be found in microstructural ...
Contact pressure and sliding velocity ranges in sheet metal forming simulations
(2021)
In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ...
Hardening prediction of diverse materials using the Digital Image Correlation technique
(Elsevier, 2018)
In recent years, due to the introduction of higher resistance materials in the automotive sector, sheet metal-forming tool-makers have been forced to deal with more challenging process designs. Therefore, the optimisation ...
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 ...
