A rather wide distribution in the angular orientation of slip lines is generally observed in various grains of a metal subjected to plastic deformation. The relative frequency of occurrence of any given slip line angle for the case of simple tension has been derived on the basis of a model of a plastically deforming polycrystal that was recently used as the basis of a theory of polyaxial stress-strain relations (the so-called slip theory of plasticity). The results are compared with experiment and conclusions are drawn as to the limitations of the model.
