Paper Title:
Formability Evaluation of Coated and Uncoated Steel Sheets with Consideration of Frictional Characteristics
  Abstract

Galvannealed steel sheets are being widely used in automotive application for better corrosion resistance. It is generally known that uncoated steel sheets have better mechanical properties than coated steel sheets due to presence of zinc coating. But frictional characteristics of coated steel sheets are very different from those of uncoated steel sheets. Therefore the study on mechanical and frictional characteristics of these steel sheets is needed. In this study, tensile test was performed to evaluate mechanical properties of coated and uncoated steel sheets. Cup drawing test was performed to measure friction-coefficient. And frictional characteristics were analyzed by using FE-analysis. The effect of mechanical and frictional properties on cup drawing was investigated. It was shown that the frictional properties more affected cup drawing.
