Abstract
Cup tests were performed on hot rolled AA3004 alloy and the profile of the ears were measured. ODF′s were determined from slices cut parallel to the cup wall at 0°, 45° and 90° to the initial rolling directions. These determinations were compared to the Taylor-Bishop-Hill deformation model using full and relaxed constraints. The measured ear profile was compared to a continuum cup height calculation and the agreement was very good.
