On the evolution of texture and yield loci in axisymmetric deformation of f.c.c. polycrystals (Q1341235)

A comprehensive analysis of texture formation and the evolution of macroscopic yield loci in face-centered cubic polycrystalline metals is presented for each of axisymmetric tension and compression, based upon the classic aggregate model of Taylor. The nonuniqueness of slip rates corresponding to rate-independent hardening theories is resolved in two alternative ways: the average slip method and minimum plastic spin. Calculations to logarithmic strains of 1.61 in tension and compression are carried out for each of four hardening rules: the ``simple theory'', Taylor hardening, the ``P.A.N. rule'', and a two-parameter rule.
