A Plasticity Framework for Forming Applications
TL;DR: In this article, the key features of a macroscopic plasticity framework applicable to numerical simulations of practical forming processes in industry are reviewed. Butler et al. proposed a framework based on mathematical concepts, physical understanding of deformation mechanisms, and experimental results.

Effect of temperature and strain rate fluctuation on forming limit curve of 5083 Al-Mg alloy sheet
TL;DR: In this article , a theoretical approach is developed to predict the temperature and strain rate dependent FLC, in which the material parameters are fitted as a function of temperature and the strain rate by response surface method (RSM).

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.

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.

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.
