Loading of mini-Nakazima specimens with a dihedral punch: Determining the strain to fracture for plane strain tension through stretch-bending
Vincent Grolleau,Vincent Grolleau,Christian C. Roth,Vincent Lafilé,Bertrand Galpin,Dirk Mohr +5 more
TL;DR: In this article, a new experimental technique is proposed for measuring the strain to fracture for sheet metal after proportional loading under plane strain conditions, which makes use of a mini-Nakazima specimen that is clamped onto a 30-mm diameter die and subjected to out-of-plane loading through a dihedral punch.

Material sensitivity and formability prediction of warm-forming magnesium alloy sheets with experimental verification
Luen Chow Chan,Xian Zheng Lu +1 more
TL;DR: In this article, a theoretical method for predicting the formability of magnesium alloy sheets at elevated temperatures by combining the Marciniak and Kuckzinsky model with the Logan-Hosford yield criterion was proposed.

Plasticity and ductile fracture modeling of an Al–Si–Mg die-cast alloy
TL;DR: In this article, the fracture behavior of an Al-Si-Mg die-cast alloy (AA365-T7, or Aural-2) was investigated using a combination of experiments and analysis.
Journal ArticleDOI
Influence of yield-surface shape in simulation of ballistic impact
TL;DR: In this paper, a high-exponent yield criterion is applied in 3D nonlinear finite element simulations of ballistic impact, and the simulation results are discussed in light of the perforation mechanisms as well as the experimental results.

Texture development and plastic anisotropy of B.C.C. strain hardening sheet metals
TL;DR: In this paper, a Taylor-like polycrystal model is adopted to investigate the plastic behavior of body centered cubic (b.c.) sheet metals under plane-strain compression and the subsequent in-plane biaxial stretching conditions.

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.
