The split-ring test provides a simple benchmark for correlating springback obtained by finite
element analysis (FEA) with experimental measurements. This test consists in cutting a ring
specimen from a full drawn cup and then to split the ring longitudinally along a radial plane.
The difference between the ring diameters, before and after splitting, gives a direct measure
of the springback phenomenon, and indirectly, of the amount of residual stresses in the
drawn cup. In this paper, the numerical simulation of the deep drawing process and splitting …
