Abstract
The material anisotropy of an aluminum sheet alloy is determined by performing tensile tests at different
angles with respect to the rolling direction (RD). To study the effect of pre-straining on the evolution of
material anisotropy, a very wide sheet is stretched to different strains in the transverse direction (TD). The
material in the central region is very close to a state of in-plane plane strain tension. Small tensile samples
are cut from the central region of the pre-strained wide sample. Tensile tests are then performed on these
small tensile samples. By comparing the differences in the flow stress vs. orientation curves between the asreceived and pre-strained sheets, the effect of pre-straining on material anisotropy is studied. Some
surprising results are observed and emphasized. Based on both the experimental and numerical studies, it
is suggested that the conventional methodology for determining material anisotropy would overestimate
the pre-straining effect and would result in a completely erroneous yield surface.
