Optimized and validated prediction of plastic yielding supported by cruciform experiments and crystal plasticity
TL;DR: In this paper, the relation between stress and strain ratios for a large number of load cases based on texture measurement was investigated, and the resulting relations were then applied separately as input parameters for the plastic yield description.

Analysis on yield loci and R values of anisotropic pure aluminium and A5083 alloy sheets
TL;DR: In this article, the effect of the scatter width of texture on the yield loci and R values of pure aluminium and A5083 alloy polycrystalline sheets with different texture components has been analyzed and examined.
Journal ArticleDOI
A planar plastic flow theory of orthotropic sheet metals and the experimental procedure for its evaluations
TL;DR: In this article, an anisotropic plasticity theory is formulated for describing planar flow behaviors of orthotropic polycrystalline sheet metals, and flow rules are derived for both the macroscopic plastic rate of deformation tensor and the macrocomopic plastic spin tensor by considering a small set of activated microscopic slips or shearing modes in a sheet metal.

XLVI. A theory of the plastic distortion of a polycrystalline aggregate under combined stresses.
J.F.W. Bishop,Rodney Hill +1 more
TL;DR: In this paper, a general relationship between stress and plastic strain in polycrystalline aggregate is derived for any metal in which individual crystals deform by slipping over preferred planes under a critical shear stress.

CXXVIII. A theoretical derivation of the plastic properties of a polycrystalline face-centred metal
J.F.W. Bishop,Rodney Hill +1 more
TL;DR: In this paper, it was shown that the work-hardness of an isotropic aggregate of face-centred cubic crystals is a function only of the total plastic work if the grains hardened equally.

The anomalous behaviour of aluminium sheet under balanced biaxial tension
John Woodthorpe,Roger Pearce +1 more
TL;DR: In this paper, the authors investigated the anomalous behavior of aluminium in uniaxial and biaxiaial tension and showed that anisotropic plasticity theory does not hold for all metals.
