Khan, A. S.; Cheng, P. An anisotropic elastic-plastic constitutive model for single and polycrystalline metals. II: Experiments and predictions concerning thin-walled tubular OFHC copper. (English) Zbl 0917.73020 Int. J. Plast. 14, No. 1-3, 209-226 (1998). Summary: Predictions based on an anisotropic elastic-plastic constitutive model proposed in the first part of this paper [see the authors, ibid. 12, No. 2, 147-162 (1996; Zbl 0858.73023)] are compared with the experimental stress and strain data on OHFC copper first under torsion to about 13% and partial unloading, and then under tension-torsion to about 10% along eight different loading paths. This paper also describes the deformation and stress of the thin-walled tubular specimen under finite deformation, the numerical implementation of the model, and the detailed procedure for determining the material parameters in the model. Finally, the model is extended to a general respresentation of the multiple directors, and the elastic-viscoplastic extension of the constitutive model is considered.
