Reflections on the dependence of plastic anisotropy on texture

Our present understanding of how anisotropic yielding behavior is related to crystallographic texture is built on a foundation laid by G.I. Taylor. Today, with the aid of computers, we can calculate the shape of yield loci from texture data and a knowledge of the slip systems. Simulation of such calculations has led to postulation of continuum yield criteria with high exponents. These criteria describe anisotropic yielding behavior much better than the quadratic criterion postulated by Hill and have been used sucessfully in analyses of metal forming.
