Summary

The purpose of the current study is to better understand the cold-rolling process through a micromechanical study. The dominant deformation mechanism is assumed to be the crystallographic slips in crystals. Specifically, the texture development in the metal sheet due to cold-rolling is simulated with a Taylor-type model, and the resultant yield loci are determined by employing Harren's self-consistent formulation to the situation in which the loading directions are not coaxial with the symmetric axes of the metal sheet. The calculations are evaluated with experimental data. Results show that these micromechanical models are quite successful in predicting the plastic behavior of metal sheets subject to moderate cold-rolling.
