In most types of sheet metal forming processes, such as drawing, stretching and bending operations, necking is the primary limiting factor in defining safe forming regions. However, it is also observed that, material failure can occur without any significant neck formation especially for non-traditional materials with relatively low formability, such as some aluminum alloys and high strength steels, . The mechanisms of such failures are not very clearly identified but it is believed that internal damage is an important parameter in these occurrences (Fig. 1).
