Stamping

TL;DR: In this article, the viability of the Small Punch Test (SPT) was analyzed to determine the yield stress evolution in any area of stamped aluminium alloy components in those cases where there is not sufficient material to carry out standard tests.

TL;DR: In this article, the nature of interfacial friction in stamping operations for three different coated sheet steels was investigated by means of a tensile strip testing system, and several relationships were ascertained for the role of the microscopic wear in determining the character of inter-surface friction during stamping processes.

TL;DR: In this article, the effect of material and process variation on the robustness of springback for a semi-cylindrical channel forming operation was investigated using AutoForm™ Sigma.

TL;DR: In this paper, an effective springback prediction in some fully three-dimensional stamping processes is carried out based on a combined approach in which an explicit finite element code has been employed to simulate the forming phase while a traditional implicit procedure has been used to analyse the springback phase.

TL;DR: In this paper, the authors developed an analytical solution to the springback of sheet metals stamped by a rigid punch and an elastic die under plane-stress deformation, where the stamping process was modelled as a three-body contact problem and the workpiece material was considered to be elastic/perfectly plastic.
