Deformation mechanisms and plasticity of ultrafine-grained Al under complex stress state revealed by digital image correlation technique
Conventional engineering stress–strain curve could not accurately describe the local deformability of the tensile necking part because the strain is calculated by assuming that the tensile specimen was deformed uniformly. In this study, we used 3D optical measuring digital image correlation to syste...
