Determining Localized Necking in Polycrystalline Sheet Metals Using the Bifurcation Phenomenon in Strain Evolution

Crystals, 2023
The forming limit is an important failure criterion for polycrystalline sheet metals when approving the forming process. Recent developments in strain measurement technology, e.g., digital image correlation (DIC), enable the strain evolution to be ...

Affecting the Determination of Forming Limit Diagram for Sheet Metals

Tikrit Journal of Engineering Sciences, 2005
The sheet metal forming is defined as the ability of metal to deform plastically (stretch forming) without necking or fracture. To control the sheets forming operation failure a diagram is used , in which the ; accepted forming , failure and critical ...

Experimental and Numerical Analysis of Forming Limit Diagram (FLD) and Forming Limit Stress Diagram (FLSD)

Materials Sciences and Applications, 2011
In this work, forming limit diagram for aluminum alloy 3105 is performed experimentally and forming limit based on stress (FLSD) calculated from strains that resulted from experimental procedure. In addition, numerical prediction by ductile fracture criteria using simulation is considered and it is shown that they are well suited with the experimental ...
