Test Methods for Sheet Metal Forming

Test methods for sheet metal forming provide characteristic values for metalworking and metal processing and include tests such as cupping tests, earing tests and hole expansion tests. 

In forming technology thin sheets are treated in various manufacturing processes such as rolling, open die forging, impact extrusion, extrusion molding, deep drawing or bending. Sheet metal forming in particular is one of the oldest production technologies. It is used to turn a flat sheet metal blank into its final shape.

Innovation is largely driven by transport technology, particularly the automotive industry. Increasing demands on sheet metal materials under the general heading of lightweight construction have led to the development of high-strength and ultra high-strength steel materials, although their reduced ductility and higher elastic recovery are setting new challenges for forming technology and process control.
