%T Mixed-Mode Deformation and Failure of a Magnesium Sheet Quantified using a Modified Arcan Fixture

%X The anisotropic plastic deformation and the failure behaviour of a rolled magnesium sheet is quantified by means of a modified Arcan loading device. Combined mode I/II loadings are applied at room temperature. Anti-buckling guides enforce parallel motion of the fixture. The evolution of local strain fields during loading is analysed by means of digital image correlation. Two target functions are constructed from each test: one including the kinetic, another describing the kinematical response. The failure strain as a function of the loading direction and sheet orientation is quantified. It is shown that the failure mechanism is independent of the loading angle. Guidelines for future constitutive model developments are provided in terms of the exploration of the samples motion, the uniformity of strain fields and their respective significance.
