Possibilites of using the Erichsen test for determination of forming limit diagram and its utilization for hydroforming

, 2017
Forming limit diagrams (FLD) are used to determine process limitations in sheet metal forming, i.e. as a level of formability assisting in the estimation of stamping characteristics. This paper deals with the experimental determination of a forming limit

Forming Limit Curve Determination of a DP-780 Steel Sheet [PDF]

Procedia Materials Science, 2015
In the present work, the forming limit curve (FLC) of a 1.1mm thick DP-780 steel sheet is evaluated. The full FLC determination involved tensile tests of planar samples with different notch geometries – providing data in the tension-compression range ...

Forming Limit Curve (FLC) and Fracture Mechanism of Newly Developed Low‐Carbon Low‐Silicon TRIP Steel

steel research international, 2007
The Forming‐Limited Diagram (FLD) of intercritically annealed 0.11C‐1.65Mn‐0.62Si TRIP‐assisted steel was investigated. The high FLD0 value of this new low carbon TRIP steel was indicative of a superior formability. The micro‐structural changes during deformation and fracture were studied in detail.

Modelling of Metal Formability in Forming Processes (Forming Limit Curves-FLC)

2003
The basic purpose of formability modelling is the defining of mathematical models that are indispensable for simulation and determination of the formability limit of metals, that is, the limiting degree of deformation in forming processes. The results obtained indicate that the formability limit of metals is a great extent dependent on the state of ...
