circular blank during the deep-drawing process are obtained analyticaly to improve upon previously given results. In addition to critical conditions for onset of elastic wrinkling of the flange, the elastic limitation of the material is also be considered...

In deep drawing process, the blank holder plays a key role in adjustment of metal flow into the die cavity.Moreover, the quality of drawn parts is extremely affected by this flow. There are two methods of treating the blank holder in deep drawing...

In this paper to predict the critical conditions for onset of elastic-plastic wrinkling of flange of a two-layered circular blank during the deep-drawing process a closed-form semianalytical elastic-plastic solution using Tresca yield criterion...

In deep drawing process, blank holder plays a key role in regulating the amount of metal flow into the die cavity and also the quality of drawn parts are extremely affected by this flow. There are two methods of treating the blank holder in deep...

Recently, the production of thinner products using deep drawing process is one of the most important needs in industries. It is known that the draw-ability of sheet metals is significantly affected by blank holder; hence, designing a new blank...

. This technique leads to the critical conditions for the onset of the elastic/plastic wrinkling of the flange during the deep-drawing process. Tresca yield criterion along with deformation theory of plasticity are utilized and the material of the plate is assumed...

Based on the two-dimensional plane stress wrinkling model of an elastic-plastic annular plate and a bifurcation functional from Hill\\\\\\\\\\\\\\'s general theory of uniqueness in polar coordinates, the critical

conditions ...

. This technique leads to the critical conditions for the onset of

the plastic wrinkling of flange during the deep drawing process. To find this solution, the Tresca yield

criterion along with plastic deformation theory are employed. The material...
