Anisotropic plastic deformation of extruded aluminum alloy tube under axial forces and internal pressure
TL;DR: In this paper, anisotropic plastic deformation behavior of extruded 5000 series aluminum alloy tubes, A5154-H112, of 76 mm outer diameter and 3.9 mm wall thickness is investigated, using a servo-controlled tension-internal pressure testing machine.

Determination of anisotropy and material hardening for aluminum sheet metal
TL;DR: In this article, the authors used a combination of experiment and analysis to extract the material response at much larger strains by accurately following the deformation in the necked region of a custom tensile test specimen.

Evaluation of associated and non-associated quadratic plasticity models for advanced high strength steel sheets under multi-axial loading
TL;DR: In this article, the authors evaluated the accuracy of quadratic plane stress plasticity models for a dual phase and a TRIP-assisted steel and found that both associated and non-associated models provided good estimates of the stress-strain response under multi-axial loading.
Journal ArticleDOI
On constitutive modeling for springback analysis
TL;DR: In this paper, the influence of constitutive modeling for springback simulations is analyzed for four different materials in the rolling-, transverse, and diagonal directions of a simple U-bend.

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.
