Abstract: A simple criterion for predicting the initiation of central burst in extrusion is proposed. The geometric conditions to avoid central bursting are predicted by using the proposed criterion under ...

Abstract: Incremental sheet metal forming (ISMF) has demonstrated its great potential to form complex three-dimensional parts without using a component specific tooling. The die-less nature in incremental ...

Abstract: 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 ...

Abstract: A process analysis model to determine the limiting drawing ratio for the first draw as well as for redraws is presented considering the effects of normal anisotropy, co-efficient of friction, ...
