Estimation of yield function for anisotropic aggregate of FCC crystallites
In this paper, a simple but approximate yield surface for single FCC crystals was given in the Hill criterion form by applying the Schmid law and the nonlinear optimization theory. It was assumed mat all FCC crystallites in a polycrystal have the same (current) critical resolved shear stress for slip, and a yield function was derived through orientational averaging of all FCC crystallites yield surfaces in the polycrystal. The effect of crystallography on the yield function was described by the orientation distribution function.
