Strain propagation instability criterion is used to evaluate the limit strains from the finite element simulations. SAE 1006, material is used in this study and 7 different specimen geometries are analyzed. Furthermore, FLD's are also predicted by theoretical approaches namely; Keeler's model, maximum load instability criterion, Swift-Hill model and Storen-Rice model. At the end of the study, the calculated FLD's are compared with the experimental results. © 2011 IBF (RWTH Aachen) & IUL (TU Dortmund).eninfo:eu-repo/semantics/closedAccessFinite element methodForming limit diagramNakazima testSheet metal formingStrain propagationPrediction of plastic instability and forming limits in sheet metal formingConference ObjectN/AN/A927932
