Summary Comparisons are made between predictions from a multi-surface representation of the hardening behaviour in polycrystalline materials and experimental results. In general, good agreement is found for the deformation behaviour, i.e. non-linear stress-strain response, a rotation in the plastic strain path and the Bauschinger effect, under stress paths which change direction. It is further shown that the model supplies more reliable predictions to the observed behaviour than those corresponding to the isotropic and kinematic hardening rules. The valid range of application for the latter rules is also clarified. The limitations of the multi-surface model, in particular, are discussed in respect of initial material anisotropy and from a cyclic loading test with ratcheting.
