Lightweight sheet metals are attractive for aerospace and automotive applications due to
their exceptional properties, such as low density and high strength. Sheet metal forming …

In sheet metal forming processes, formability is a critical material property that needs to be
estimated before the production of forming parts. Some popular tools used in the literature to …

The present study investigated the size effect on the formability of ultra-thin metallic bipolar
plate for proton exchange membrane (PEM) fuel cell by crystal plasticity finite element …

Abstract The Forming Limit Curve (FLC), which describes the maximum applicable strain
before localization, depends on the particular material, but also on the applied load and …

Abstract An advanced Crystal Plasticity Finite Element (CPFE) approach is developed to
accurately predict the ductility limit strains of thin metal sheets. This method uses …

The forming limit of sheets usually corresponds to the strain accumulation before localized
necking and is closely related to the loading state. In the viscous pressure forming (VPF) …

To accurately identify the limit strains and improve the prediction accuracy of forming limits
for sheet metal, a novel three-dimensional MK model by integrating GTN model is …

The through-thickness normal stress and the friction stress in the forming process have
significant impact on the forming limit curves (FLCs) of sheet metal. In this work, the through …

In the present study, the anisotropic formability and underlying deformation mechanism of
near-α TA32 titanium alloy sheet under continuous nonlinear strain paths (CNSPs) at high …

This study clarified the effects of the chosen hardening model, through-thickness normal
stress, and non-linear strain path on the precision of forming limit diagram (FLD). The …
