Forming of magnesium and its alloys
TL;DR: In this paper, the authors examined the formability of magnesium base alloys through the prism of the tensile test and found that they typically display strain hardening exponents and forming limit curves marginally lower than comparable aluminium base alloy.

Robust multi objective optimization of anisotropic yield function coefficients
TL;DR: In this article, a multi objective genetic algorithm (MultiGA) based approach was implemented to obtain coefficients of anisotropic yield functions by simultaneous error minimization for yield stresses and R-values.

Effect of Anisotropic Plasticity on Mixed Mode Interface Crack Growth
TL;DR: In this paper, a phenomenological elastic-viscoplastic material model is applied, using one of two different anisotropic yield criteria to account for the plastic anisotropy.
Modelling macroscopic imperfections for the prediction of flow localization and fracture
Frédéric Barlat,Owen Richmond +1 more
TL;DR: In this paper, a model that evaluates the void volume fraction in the imperfection is developed more rigorously, and the forming limit diagram for a dual phase-steel is calculated using the damage-based imperfection calculation and validated with experimental results.

Towards the fracture prediction of turbomachinery disks : a contribution of the digital image correlation
TL;DR: This thesis addresses the amelioration of the burst prediction of turbo-engines rotating parts by identifying the material behaviour up fracture under multi-axial loading and the identification of the local condition at failure and using an integrated digital image correlation approach to accomplish this.

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.
