Experiences from experimental and numerical springback studies of a semi-industrial forming tool
TL;DR: In this article, a semi-industrial tool was designed to catch those springback problems that are encountered in the forming of real industrial, parts, which can be found in typical forming tools, such as several draw radius steps and changeover in section geometries.

Evaluation of biaxial flow stress based on elasto-viscoplastic self-consistent analysis of X-ray diffraction measurements
Youngung Jeong,Youngung Jeong,Thomas Gnäupel-Herold,Frédéric Barlat,Mark A. Iadicola,Adam A. Creuziger,Myoung-Gyu Lee +6 more
TL;DR: In this article, an elasto-viscoplastic self-consistent (EVPSC) crystal plasticity model was used to predict the stress factors and intergranular (IG) strains.

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.

J. M. Rosenberg,H. R. Piehler +1 more
TL;DR: In this article, the Taylor factor and the corresponding lattice rotations for tension or compression have been computed for grains of various orientations postulated to slip on arbitrary planes in 〈111〉 directions.

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.
