High process stability is a key to reducing scrap and therefore the ecological footprint during...

... of the developed constitutive model and the fracture criterion, a deep drawing test of the PET-coated sheet metal was conducted. The film cracking predicted by the anisotropic fracture criterion agreed well with measurements. In the lamination, the film and the steel sheet are roll bonded at warm temperatures...

... types of lubricants were evaluated using strip draw test (SDT) and deep draw test (DDT) for stamping of galvannealed steel sheets. Finite element (FE) simulations were carried out to determine the coefficient of friction at tool-work piece interface during deep drawing under different lubrication...

...Xu Yong-chao; Han Cong; Yuan Shijian For deep cylindrical cups with a large height-diameter ratio, it is difficult to be hydroformed in one stroke. Reverse deep drawing is necessary after deep drawing. Deformation optimization was performed to achieve a large drawing ratio and uniform thickness...

...M. R. Morovvati; B. Mollaei-Dariani; M. Haddadzadeh The initial blank in the deep drawing process has a simple shape. After drawing, its perimeter shape becomes very complex. If the initial blank shape is designed in such a way that it is formed into the desired shape after the drawing process...

We proposed to realize a global optimization of a deep drawing industrial progression (made of several stages) for a cup manufacture. The objectives of the process were the thickness decrease...

... procedure consists of deep drawing a circular 6111-T4 aluminum alloy into a cylindrical cup of 55 mm depth, crosscutting nine rings each of 5 mm wide from the cup, splitting the rings, and measuring their opening displacement, i.e., the springback amount.
