Abstract
A small-cube compression test is proposed to experimentally determine local properties of plastic anisotropy. Small cube specimens are cut out of a thick plate in various positions. After the test the shape of a compressed plane on the specimen changes from a square into a rectangle due to plastic anisotropy. The six anisotropic constants in Hill's yield criterion are calculated from the ratios of width-to-length strains on the compressed rectangular plane. The deformed shapes of a cylinder and a block after upsetting can be precisely simulated by considering the local properties of plastic anisotropy.
