INVESTIGATION OF THE EFFECT OF ALLOY ELEMENTS IN STEEL SHEETS USED IN THE AUTOMOTIVE INDUSTRY

Abstract

In this study, analyses were made using the finite element method and the formability were examined of six different materials used in the automotive industry. Deep drawing simulation was made of materials with a specific geometry and initial thickness of 1.5 mm and forming limit diagrams were obtained. The formabilities were compared over the diagrams plotted separately for each material and the deformation difficulties were evaluated. According to the analysis results, It was determined Niobium, Titanium and Vanadium elements had negative effects and Aluminum element had a positive effect on formability.
