This study aimed to investigate the effect of elevated temperatures, combined with the blank
holder force and punch radius, on the thickness distribution of cylindrical cups in the deep …

Trustworthy numerical simulations in sheet metal forming are highly dependent on accurate
prediction of yielding response of a material. Thus, the present work is mainly focused on …

Forming limit curves at neck (FLCN) and forming limit curves at fracture (FLCF) for various
steel sheets were determined from a hemispherical punch stretching. The measured FLCF …

To predict accurately the forming limit in sheet metal forming, the combination of FE
simulation with tension tests is adopted in this paper to determine the material constants p …

The macroscopic fracture behavior of metal sheet forming process highly depends on
microscopic fracture mechanism, thus establishing a ductile fracture criterion reflecting …

One of the major manufacturing processes to produce components from flat sheets is
forming. The automotive industry is one of the highest markets for stamped parts and is, thus …
