PUNCHING TEST FOR THE MECHANICAL CHARACTERIZATION OF METAL SHEET FORMING PROCESSES

Abstract

Metal forming includes several manufacturing processes in which plastic deformation is used to change the shape of metal parts. The deformation is the result of the use of a tool, generally a die, that applies forces that exceed the yield strength of the metal, that is, the metal is deformed to take the shape determined by the die. In general, a compressive stress is applied to plastically deform the metal, however some processes bend or cut the metal.
