Springback Determination By Springback Index Approach
SAE Technical Paper Series, 2005<div class="htmlview paragraph">A new mechanical parameter, Springback Index (SBI), is proposed to reflect the magnitude of sheet-metal springback at a given flow stress level. Through conducting Tension-Unloading-Reloading (TUR) tests and measuring the Effective Unloading Modulus (EUM) Parameter, which is defined as the ratio of the non-linear ...

When producing a part, either by deep drawing, stretch forming or bending, flat sheet is transformed into a design shape and dimension. At the end of the forming process, when the part has been released from the forces of the forming tool, there is a distortion in the shape and dimension of the formed oart. This distortion is termed springback.

Springback, the elastically-driven change of shape of a part after forming, has been simulated with 2-D and 3-D finite element modeling. Simulations using solid and shell elements have been compared with draw-bend measurements presented in a companion paper.

Robust springback compensation
AIP Conference Proceedings, 2013Springback simulation and springback compensation are more and more applied in productive use of die engineering. In order to successfully compensate a tool accurate springback results are needed as well as an effective compensation approach. In this paper a methodology has been introduce in order to effectively compensate tools. First step is the full
