Flanging

TL;DR: In this paper, a computer aided design method for straight flanging using finite element method is presented, and the predictions have been validated with some laboratory experiments, and this method was applied on a specific type of flanging in which the edge is coined at the end of the operation.

TL;DR: In this paper, a stretch flanging operation on a flat circular sheet with a hole in the center has been analyzed by means of a total strain membrane theory of rigid-plasticity which incorporates strain hardening and anisotropy in the direction normal to the sheet.

TL;DR: In this paper, the influence of process variables, such as die shoulder radius, punch-die clearance, punch nose radius, pad force and material properties, on straight flanging was discussed.

TL;DR: In this paper, a numerical and experimental investigation on the field of expansion and reduction of thin-walled tubes using a die with the objective of dealing with existing gaps in knowledge related to the influence of process parameters on the formability limits induced by ductile fracture, wrinkling and local buckling.
