Investigation of the effects of deformation speed on the mechanical properties and deep drawing process of DP600 and DP780 sheet metal [Deformasyon hizinin DP600 ve DP780 sac malzemelerin mekanik özelliklerine ve derin çekme işlemine etkilerinin incelenmesi]

In this study,the effects of deformation speed on the deep drawing process were investigated for dp600 and dp780 sheet materials that are widely preferred in the automotive industry. for this purpose,the uniaxial tensile tests were performed at the different deformation speeds to determine mechanical properties of materials. deep drawing analyzes were carried out at different deformation speed by using finite element method. analysis results show that the increase in the deformation speed cause to increase the amount of springback,forming force and the sheet thickness in the flanks while increasing thinning at upper area of the product are determined.
