...Anupam Agrawal; N. Venkata Reddy; P. M. Dixit Wrinkling in the flange region has been observed during redrawing operation by a few researchers. In the present work an analysis methodology, based on a combination of upper bound and energy approaches, is proposed for the prediction of number...

... defect in forging of axially symmetrical flanged components is systematically investigated. A FE model to study the root-cause of the defect based on the material flow behavior is developed and a defect formation mechanism is revealed. The variation of material flow behavior with the changes of part...

... the application scopes of the inverse approach. Based on the updated approach, a trimming line design and flanging analysis method are proposed. These methods can be used in autopanel virtual manufacturing, rapid design, and manufacturing as quick simulation and optimization tools. Some practical examples...

... of application, stretch flange forming of these aluminum alloy sheets is considered. The AA5754 stretch flange displays a circumferential crack during failure, whereas the AA5182 stretch flange fails through a radial crack at the edge of the cutout. It is shown that the necking predictions obtained using...
