A study of sheet metal

Hole-flanging is a crucial operation in sheet metal forming technology, where the material around a pre-fabricated hole is deformed by a spherical, conical, or cylindrical punch to create a flanged hole wall. This study aims to determine the limiting hole-flanging coefficient of AA1050-0 aluminum alloy sheet using the Cockroft-Latham ductile fracture criterion.
