    Abstract

    The stress-strain response of aluminium sheet has been determined by a novel plane strain compression test on laminated samples up to equivalent strains of 1.2. The test sample is composed of several sheet layers glued together, machined to shape, and then compressed in a lubricated channel die along the “thin” directions. This simple test has been validated by a comparison of finite element simulations and experimental results. The stress-strain curves can be considered accurate up to strains of 1.2.
