Abstract

The level and shape of the FLD depend on many and different factors. The experimental investigations point out that the prediction of die plastic instability depends on the sheet thickness, the strain path, the strain rate, the material properties and the used constitutive equation. This study is devoted to analyse the influence of the basic material properties and forming conditions on the level and shape of the FLD.
