Bending industrial processes of complex elements inevitably require analysis of stress and strain in the contact zone of tools and materials if an accurate geometry and fast implementation. One of the effects that inevitably accompanies the elastic springback of the folded parts. Residual stresses always conditioned by changing the geometry of the finished part after leaving the tools that must be included in the construction tool positions that directly affect the final geometry. Knowing the springback value and its analysis by finite element method greatly facilitates the entire design process technology in both simple and highly complex finished components.
