Hole Expansion Test

The hole expansion test is a test method applied in the metalworking industry and is used to determine the ductility of the edges on punched sheet metal.

Particularly in the case of high strength steels, forming technology presents new challenges due to the formation of edge cracks. Shearing reduces the forming capacity of the edge.
