A numerical study on establishing the forming limit curve and indicating the formability of complex shape in incremental sheet forming process

International Journal of Precision Engineering and Manufacturing, 2013
In order to obtain a final sound product by the incremental sheet forming (ISF) process for complex shape using cold rolled steel material, the limit curve based on the maximum wall angle versus maximum deformed height was established utilizing finite element method (FEM) simulations for several square shapes with various wall angles. The forming limit

Formability prediction of high‐strength steel sheet using experimental, analytical and theoretical analysis based on strain and stress forming limit curves and its application to automotive forming parts

Materialwissenschaft und Werkstofftechnik, 2023
AbstractIn this work, the high‐strength steel (HSS) sheet dual‐phase 440 (DP440) were conducted to establish the forming limit curve (FLC) and analytical forming limit stress curve (FLSC) obtained from experimental forming limit curve. First, the Nakajima stretch forming examination was carried out to obtain forming limit curve of investigated sheet ...

Formability Limiting Curve of Mild Steel by Explosive Forming

1990
At the advent of increasing interest in high velocity forming techniques, the knowledge of maximum extent of formation without the risk of any failure becomes necessary. A Formability Limit Curve will represent a critical level curve separating FAIL region from SAFE region.

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 ...
