Deformations are measured with 3D digital image correlation. The thin-walled test section and use of DIC allow the stress and local deformations to be established from experimental measurements alone. The stress and deformation within the test section are uniform until a load maximum is reached, beyond which deformation localizes into a circumferential band with width the order of the wall thickness. A series of experiments show that the strain at failure monotonically increases as the triaxiality decreases, in contrast to previously-reported results for this alloy. The strains at failure are also significantly larger than previously-reported values. Numerical simulations demonstrate that the deformation, including localization, can be reproduced reasonably accurately to large strains with suitably-calibrated plasticity models.
