Abstract

Metallic material formability study is critical in a variety of industrial areas, including automotive, aerospace, and manufacturing. The present study aims to investigate the formability properties of steel and copper-based alloy sheets using the Erichsen cupping test machine, an established technique for evaluating sheet metal formability. The process involves manufacturing identical steel and copper-based alloy specimens and subjecting them to the Erichsen cupping test. The test determines the maximum deformation depth of a metal sheet before fracture, providing significant information on its formability. The test results were examined and compared to identify the differences in formability between steel and copper-based alloy sheets. The formability properties of each material factor, such as strain distribution, ductility, and fracture behavior, were studied. The study reveals that steel has greater formability than copper-based alloys. This conclusion is based on the fact that when steel sheets are tested using the Erichsen cupping test, they may endure a greater degree of deformation before fracturing. The strain distribution study demonstrates the distinct ways the two materials respond to the deformation process, exhibiting their differential formability characteristics. The study offers precise information on the maximum deformation depth of copper-based alloy and steel sheets before fracture. This quantity acts as an evident predictor of formability. Steel sheets have greater deformation depths than copper-based alloy, which indicates superior formability when measured in terms of maximum deformation before failure, according to the results.
