Abstract:

Springback is the most important failure mode for the sheet metal parts obtained by U-bending.Numerous studies have been conducted in order to develop a method for an accurate prediction andlimitation or elimination of this phenomenon. As there is not possible to use an analitical method for thisproblem, numerical methods, especially finite element method, have been developed and applied for sheetmetal forming. This paper uses U-bending simulation by finite element analysis combined with a fractionalfactorial design in order to establish a method for the reduction of springback parameters.

Keywords:

springback, U-bending, finite element method, fractional factorial design.
