Abstract The fracture toughness of a thin-sheet V-1167RDTV aluminum alloy is investigated by digital image correlation method. The ways of correct estimation of the stress intensity coefficients obtained by calculating the displacement fields by the Williams equation are found. Buckling criteria are quantitatively determined, and a crack propagation resistance curve (R-curve) is plotted for static loading.
