DIFFERENT BEHAVIORS OF COPPER AND STEEL IN HYDROSTATIC FORMING FOR SHEET METAL

Abstract

In hydrostatic forming for thin-shell part, material is one of the factors influencing forming process and part quality. Thus, research on material behavior in hydrostatic forming process needs to be paid attention. At present, typical thin-shell parts in a car are manufactured of steel, some other small parts are of copper. Finding an optimal suitable method for forming parts of these materials is also a solution to reduce energy consumption and production cost, which are interested in the most. Therefore, these two kinds of material are used to investigate their behavior, or their deformation by hydrostatic forming for sheet metal. Comparison between their deformation partly explains why steel is used more widely than copper.
