Investigation of evolving yield surfaces of dual-phase steels
Yong Hou,Junying Min,Nan Guo,Jianping Lin,John E. Carsley,Thomas B. Stoughton,Heinrich Traphöner,Till Clausmeyer,A. Erman Tekkaya +8 more
TL;DR: In this article, the authors describe the evolving yield behavior of dual-phase steels during plastic deformation characterized for ten loading paths using a series of mechanical tests including uniaxial tension, uniaaxial compression, in-plane torsion and cruciform bao-cial tension with the aid of digital image correlation techniques.

Shear confusion: Identification of the appropriate equivalent strain in simple shear using the logarithmic strain measure
Clifford Butcher,A. Abedini +1 more
TL;DR: In this article, a closed-form solution for the work-conjugate equivalent strain for an arbitrary yield function was derived for simple shear loading that is readily amenable to experimental characterization and is entirely consistent with the logarithmic strain measure.

A method of predicting macroscopic yield strength of polycrystalline metals subjected to plastic forming by micro–macro de-coupling scheme
Ikumu Watanabe,Kenjiro Terada +1 more
TL;DR: In this paper, a method of predicting the macroscopic yield strength of polycrystalline metals subjected to plastic forming is introduced, which hinges on the reliability of the micro-macro decoupling scheme for solving the corresponding two-scale boundary value problem.

Prediction of forming limit curves of sheet metals using Hill's 1993 user-friendly yield criterion of anisotropic materials
Siguang Xu,K.J. Weinmann +1 more
TL;DR: In this paper, an attempt is made to analyze forming limits in sheet metals based on Hill's yield criterion and the M-K approach, which utilizes five independent material parameters in representing the yield locus.

On the modelling of plastic anisotropy, asymmetry and directional hardening of commercially pure titanium: A planar Fourier series based approach
TL;DR: In this paper, a novel approach to define a very flexible, three-dimensional yield criterion is proposed, where deviatoric stresses are mapped from five-dimensional space into a reduced threedimensional space (the material is assumed to show an isotropic response under shear loading).

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.
