Abstract:
For many reasons, the well-known Forming Limit Diagram (FLD) is still widely used by sheet metal forming industry and academia to identify stretching failure. Based on findings from micromechanical studies, a Ductile Failure Criterion (DFC) was proposed. Under proportion strain path assumption, a method to calculate Forming Limit Curve (FLC) by using tension test only is derived from this DFC. The method was validated by calculating FLCs for several sheet metal materials different in grades and initial sheet thickness. The calculated FLCs are further used to predict failure in drawing processe. Comparison shows that the prediction by using those calculated FLCs matches quite well with experimental observations.
