An experimental test system has been developed to support numerical modeling analysis of sheet metal failure. The system consists of a planar biaxial test frame, cruciform specimens and grips, and custom software to control the frame's actuators. Thin aluminum 6061-0 specimens are loaded to the point of incipient failure under different biaxial stress ratios. The data from these tests are used in validating a constitutive plasticity/failure model for aluminum 6061-0 by comparison with finite element predictions. 9 refs, 8 figs, 2 tabs.
