On the Accuracy of the Taylor Assumption in Polycrystalline Plasticity

  • Conference paper
Anisotropy and Localization of Plastic Deformation

Abstract

The accuracy of a Taylor-type polycrystal constitutive model, in which compatibility is satisfied but equilibrium between grains is violated, is evaluated by comparing the predictions from this model for the overall stress-strain response and crystallographic texture evolution during simple shear of fcc metals against predictions from a full finite element model in which both compatibility and equilibrium in the polycrystalline aggregate are satisfied. Our calculations show that the Taylor-type model is in reasonable first-order agreement with the results of the finite element calculations and also with the results from corresponding physical experiments on single-phase copper.
