TLDR
In this paper, an upper-bound model which combines a least-shear analysis and Piehler's maximum virtual work analysis was proposed to determine axisymmetric deformation.About:

Experimental investigations on extruded 6063 aluminium alloy tubes under complex tension-compression stress states
TL;DR: In this paper, the axial feeding force was considered to impart a tension-compression stress state which could affect the final geometry of hydroformed tubes and the deformation behavior of aluminum alloy tubes under internal pressure and axial compressive force.
Journal ArticleDOI
Reflections on the dependence of plastic anisotropy on texture
TL;DR: In this article, the shape of yield loci from texture data and a knowledge of the slip system is used to postulate a continuum yield criteria with high exponents, which describe anisotropic yielding behavior much better than the quadratic criterion postulated by Hill and have been used sucessfully in analyses of metal forming.

Simulations of a top-hat section subjected to axial crushing taking into account material and geometry variations
TL;DR: Fyllingen et al. as discussed by the authors performed simulations of top-hat thin-walled sections of dual-phase steel DP800 subjected to axial crushing taking into account process history and measured geometric imperfections, thickness variations and material variations.

Modeling and simulation of the forming of aluminum sheet alloys
J. W. Yoon,F. Barlat +1 more
TL;DR: In this article, a numerical simulation of the forming of aluminum alloy sheet metals is presented, where macroscopic and microscopic aspects of the plastic behavior of aluminum alloys are reviewed first and then discussed to cover theoretical and implementation aspects of sheet metal forming simulation.

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.

Calculation of the taylor factor and lattice rotations for bcc metals deforming by pencil glide
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.
