Abstract

Abstract- It is very important in terms of cost and time to correctly estimate and compensate for the springback during sheet

metal forming. Experimental and analytical studies are available in the literature for the prediction of springback

propagation. The multiplicity and diversity of the parameters that cause springback makes it difficult to analytical modeling

of the springback. On the other hand, the development of finite element method package programs over the years has made

the end-of-line method indispensable for industrial and academic work. However, the results obtained using the finite

element simulation method should be verified by experimental results. In this study, the amount of springback was tried to

be reduced by the application of the draw beads which is used in sheet metal die industry in the process of deep drawing of

the vehicle body part having a tensile strength value of 270 MPa. Finite element simulation results and the results obtained in

the real environment has been validated. In addition to the work done, the effects of material thickness and modulus of

elasticity on the amount of springback were investigated.
