Advances in plastic anisotropy and forming limits in sheet metal forming
TL;DR: In this article, the authors present new phenomenological yield criteria developed in the last decade, which are able to describe the anisotropic response of sheet metals, and, on the other hand, new models and experiments to predict/determine the forming limit curves.

Numerical simulation modeling of tailor welded blank forming
TL;DR: In this paper, a review of the numerical modeling of TWBs is presented, including finite element method modeling of the weld zone, material models used for numerical modeling, theoretical failure techniques and their application to TWBs, and the design and optimization of TWB.

An Experimental Methodology to Characterize the Plasticity of Sheet Metals from Uniaxial to Plane Strain Tension
TL;DR: In this article, a novel experimental integration methodology was developed to exploit these stress and strain gradients to locally calibrate the arc of an anisotropic yield surface from uniaxial-to-plane strain tension.
Yield criteria for anisotropic elasto-plastic metals
TL;DR: A submitted manuscript is the version of the article upon submission and before peer-review as discussed by the authors, while a published version is the final layout of the paper including the volume, issue and page numbers.

Generalization of the marciniak-kuczynski defect model for predicting forming limit diagrams
P. Van Houtte,Laszlo S. Toth +1 more
TL;DR: In this article, a numerical code has been constructed to calculate Forming Limit Diagrams (FLD) of arbitrarily anisotropic crystalline sheet metals to detect the occurence of strain localization, the Marciniak-Kuczinsky defect model has been adopted.

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.
