Abstract

In this study, it
is aimed to make comparison of four different steel sheet materials that are
widely used in deep drawing applications by taking blank holder force and
friction conditions into account. Comparison is made between a standard steel
which is generally used in white goods manufacturing (DC01), an ultralow carbon
steel (DC04), a deep drawing steel suitable for cold forming (DD13) and an
extra deep drawing steel resistant to ageing (DD14), which are preferred when
manufacturing a part by deep drawing, if there is not any special material
requirements. The purpose of this study is to make selection between these
mentioned materials easier. Simufact.forming, a plastic deformation analysis
software based on finite element method, and material database of the software
was used in the conducted analyzes. Various blank holder forces were applied
and friction conditions were changed for each material. By investigating
obtained results, it was seen that there is a significant difference between
deep drawing behavior of these materials and DD14 has high deep drawability
even under high blank holder forces with low energy. Moreover, it was observed
that friction conditions have a significant influence on effectiveness of deep
drawing process.
