Abstract
One critical problem of sheet formed products is its dimensional accuracy. This is related to springback (elastic recovery), after forming load releasing. It may happen in any forming process; however, it is easier noted and quantified in bending process. Needless to say that this problem is undesirable since it affects assemblies, mainly at aeronautics industry [1]. Although, literature provides some models for predicting springback in conventional bending, this is not the case for non conventional bending using polyurethanic die and that's why the process has been treated on trial and error basis at shop, implying in product discharge. So, this work intends to present a theoretical model for predicting springback. Model validation has been done by experimental results. Predicted values are in a good agreement with these latter. © 2010 Springer-Verlag France.
