Consideration of crystallographic texture has lead to a much better understanding of anisotopic yielding behavior than yield criteria postulated without regard to deformation mechanisms. Continuum anisotropic yield criteria have been developed to simulate the results of calculations based on the crystallographic nature of slip. These criteria, which involve high stress exponents, describe actual forming behavior much better than the quadratic yield criterion postulated by Hill. Today it is possible to calculate anisotropic yielding behavior directly from texture data, although for metal forming analyses, some other means must be used to characterize the strain-hardening behavior.
