ZwickRoell Testing Solution for Hole Expanding Test to ISO 16630

The hole expansion test is a test method applied in the metalworking industry and is used to determine the ductility of the edges of punched sheet metal. In the case of high strength steels, forming technology presents new challenges due to the formation of edge cracks. In order to make manufacturing processes more reliable, characteristic values for edge crack sensitivity are determined using the hole expansion test. This webinar will give an overview of this solution for sheet metal testing machines.
