Abstract
Two-stage sequences of simple shear performed on low carbon steel sheets were supplemented by texture measurements. A detailed analysis of the texture evolution during the simple shear sequences was realized by studying the orientation distribution functions. The calculation of the orientation stability map (using the classical viscoplastic Taylor model) allows explanation of the observed texture development: the initial texture is shown to be partly stable and hence the measured textures differ from the usually reported ones. The influence of the texture evolution on the shape of the stress-strain curves, as well as on the remaining symmetries of the material, is also discussed. In particular, it is demonstrated that both intragranular and geometrical contributions have to be considered to explain the shape of the stress-strain curves after a strain path change.
