Cyystallographic analysis of the influence of stress state on earing behavior in deep drawing of Face-centered cubic metals

摘要

The Tucker method of earing analysis is modified by introducing the normalized radial strain to represent the radial anisotropic deformation in deep drawing. By means of this method associated with different assumptions on the radial strain contribution of slip, the influence of stress state in the flange of blank on earing behavior is analyzed in detail for some important ideal orientations in face-centered cubic (fcc) metal sheets.
