A Study of Anisotropic Workhardening

This paper deals with the stress-strain curves of single crystal and polycrystal considering the workhardening and the anisotropy which is due to the difference of workhardening on each slip system. The results obtained are summarized as follows: 1) The equations of workhardening on each slip system are derived according to the dislocation theory. 2) And it is found that the stress-strain curves of Cu single crystal and polycrystal calculated by using the workhardening equation with proper coefficients agree well with the experimental values.
