Anisotropy, tension-compression asymmetry and texture evolution of a rare-earth-containing magnesium alloy sheet, ZEK100, at different strain rates and temperatures: Experiments and modeling
TL;DR: In this paper, the mechanical response and texture evolution of rare-earth-containing magnesium alloy sheet, ZEK100, are measured under uniaxial (tension and compression) loading along the rolling direction (RD), 45° to rolling direction(DD), transverse direction (TD) and normal direction (ND), at the strain rate of 10 −4 to 3 ǫ 10 3 s −1, and temperatures of 22 Â c and 150 Â C.

Application of artificial neural networks in micromechanics for polycrystalline metals
TL;DR: In this paper, an artificial neural network (ANN) model is coupled with a rate-dependant crystal plasticity finite element method (CPFEM) formulation to predict the stress-strain behavior and texture evolution in AA6063-T6 under uniaxial tension and simple shear.

Anisotropic and asymmetrical yielding and its distorted evolution: Modeling and applications
TL;DR: In this article, a unified continuum-based discontinuous (CBD) framework is constructed, in which SSM and SIM are introduced to capture the distorted shape of the yielding, and an interpolation approach is adopted to smoothly present the nonlinear evolution of the distorted plasticity in the full stress space.

Plastic anisotropy and the role of non-basal slip in magnesium alloy AZ31B
Sean R. Agnew,Ozgur Duygulu +1 more
TL;DR: In this paper, a combination of experimental and simulation techniques were used to investigate the plastic behavior of wrought magnesium alloy and found that an increased activity of non-basal dislocations provides a self-consistent explanation for the observed changes in the anisotropy with increasing temperature.
