Expanding pierced holes is a common forming practice and problems during these operations are not unusual. A damczyk and Michal have previously developed an equation for maximum hole expansion of HSLA steels, for holes in the sheared then deburred co

The edge formability of a spectrum of high-strength cold-rolled steels has been evaluated using the hole expansion test. The effects of edge condition, micro structure, and tensile properties on hole expansion performance were determined. Modificatio
