Abstract:The influence of stress state on earing behavior in cup drawing ofFCCmetal sheets was analyzed using the crystallographic method. The results showed that, under the partial-slip(PS) assumption, both the type and extent of earing change with the stress ratio significantly; under the total-slip(TS) assumption, the earing extent varies with the stress ratio while the earing type changes only slightly. Simple method was adopted to predict the cup heights of an aluminum single crystal sheet.
