Abstract
Three metals were subjected to zig-zag stress paths in the plastic region. The direction of the plastic strain increments suggested local distortion of the yield surface rather than the formation of a sharp corner. A stepped stress path with unloading between steps gave strain increments consistent with a distorted but smooth yield surface, rather than one with plane segments.Keywords
