Mechanical response, twinning, and texture evolution of WE43 magnesium-rare earth alloy as a function of strain rate: Experiments and multi-level crystal plasticity modeling
William G. Feather,Saeede Ghorbanpour,Daniel J. Savage,Milan Ardeljan,Mohammad Jahedi,Brandon McWilliams,Nikhil Gupta,Chongchen Xiang,Sven C. Vogel,Marko Knezevic +9 more
TL;DR: In this paper, a multi-level constitutive model for polycrystalline metals that deform by a combination of elasticity, crystallographic slip, and deformation twinning is proposed to interpret the deformation behavior of alloy WE43 as a function of strain rate.

A crystal plasticity finite element model embedding strain-rate sensitivities inherent to deformation mechanisms: Application to alloy AZ31
TL;DR: In this paper, a numerical method implemented in a crystal plasticity finite element (CPFE) model for embedding any value of the power-law exponent reflecting the true material strain-rate sensitivity is presented.

Modeling the role of local crystallographic correlations in microstructures of Ti-6Al-4V using a correlated structure visco-plastic self-consistent polycrystal plasticity formulation
Iftekhar A. Riyad,William G. Feather,Evgenii Vasilev,Ricardo A. Lebensohn,Brandon McWilliams,Adam L. Pilchak,Marko Knezevic +6 more
TL;DR: In this article, a multilevel crystal plasticity-based simulation framework for modeling mechanical response and microstructure evolution of Ti-6Al-4V with α-lath/lamellar microstructures is presented.

A numerical study into element type and mesh resolution for crystal plasticity finite element modeling of explicit grain structures
TL;DR: In this paper, a large number of massive crystal-plasticity-finite-element (CPFE) simulations are performed and post-processed to reveal the effects of element type and mesh resolution on accuracy of predicted mechanical fields over explicit grain structures.
