Investigation on the effect of curvature and sheet thickness on forming limit prediction for aluminium sheet metal alloys
Source abstract
Abstract
For characterising formability of sheet metal materials several testing methods have been developed during recent years. The most common way to estimate formability of sheet metal parts is the so called Forming Limit Diagram (FLD) method. But forming limits under bending cannot be described by the conventional FLC. This contribution reveals possibilities of an experimental characterisation of material’s bendability. Furthermore, an approach concerning the characterisation of formability under simultaneous drawing and bending for various sheet thicknesses is given.
