A biaxial test for rheological and formability identification

EPJ Web of Conferences, 2010
Accurate constitutive laws and formability limits of materials are essential for a numerical optimization of sheet forming processes. The main objective of this work is to develop a new experimental device able to give for a unique specimen a good ...

Development of the Forming Limit Diagram for AA6016-T4 at Room Temperature Using Uniaxial Tension of Notched Samples and a Biaxial Test

Crystals, 2023
Within the framework of the formability limit assessment in sheet metal forming, testing of notched tensile samples coupled with digital image correlation (DIC) has been analysed as an alternative to overcome the implications of Nakajima testing in ...

Friction influence on the AA6060 aluminium alloy formability

Fracture and Structural Integrity, 2019
Using a finite element calculation code, this work analyses the influence of friction during a stamping test conducted on the AA6060 aluminium-based alloy. The study focuses on phenomena happening when the sheet necking appears.

EXPERIMENTAL FLC DETERMINATION OF HIGH STRENGTH STEEL SHEET METAL

Acta Metallurgica Slovaca, 2015
To assess formability in sheet forming, experimentally determined Forming Limit Curves (FLC) are often used. These conventional FLCs represent the forming limits (i.e.
