Modeling the temperature dependent effect of twinning on the behavior of magnesium alloy AZ31B sheet
A. Jain,Sean R. Agnew +1 more
TL;DR: In this paper, the critical resolved shear strengths (CRSS) and hardening behaviors of deformation mechanisms were modelled using a viscoplastic self-consistent polycrystal model to model the changes in the flow stress profile, the strain anisotropy, and texture evolution.

Improvement of formability of Mg–Al–Zn alloy sheet at low temperatures using differential speed rolling
TL;DR: In this article, the differential speed rolling (DSR) with a roll speed ratio of 1.167 was carried out on an AZ31B magnesium alloy in order to investigate its effects on the formability.

Tensile characterization and constitutive modeling of AZ31B magnesium alloy sheet over wide range of strain rates and temperatures
TL;DR: In this paper, the constitutive fitting of the stress-strain curves to the widely employed Johnson-Cook material model equation is evaluated and also a new model is proposed based on a modified J-C model to account for the variation of strain hardening with strain rate.
