FORMABILITY TESTING OF SHEET METALS

The current formability tests, which evaluate ability of sheet metals to be formed into useful components successfully, are reviewed critica lly. The handing index, the anisotropy index, and the Ohio State Unive rsity Formability Test (OSUFT) index are identified as the three most important formability test results that could be used on a routine bas is by industry for grading, selecting and sorting of incoming sheet me tals for manufacturing of various components. A new computer based app roach is proposed to identify the minimum formability requirement for any sheet metal component.
