Journal ArticleDOI
Deformation twinning in AZ31: Influence on strain hardening and texture evolution
Marko Knezevic,Amanda Levinson,Ryan Harris,Raja K. Mishra,Roger D. Doherty,Surya R. Kalidindi +5 more
TL;DR: In this paper, the authors investigated the effects of deformation twinning on various aspects of plastic deformation, including the anisotropic strain-hardening rates, the tension/compression yield asymmetry, and the evolution of crystallographic texture.
Journal ArticleDOI
Strain rate and temperature effects on the selection of primary and secondary slip and twinning systems in HCP Zr
TL;DR: In this article, the authors investigated the temperature and rate dependence of slip, twinning, and secondary twinning in high-purity hexagonal close packed α-Zr over a wide range of temperatures and strain rates.
Journal ArticleDOI
Strain rate and temperature sensitive multi-level crystal plasticity model for large plastic deformation behavior: Application to AZ31 magnesium alloy
TL;DR: In this article, a multi-level constitutive model for polycrystalline metals that deform by a combination of elasticity, slip and deformation twinning was developed, where the first level uses an upper bound Taylor-type crystal plasticity (T-CP) theory to relate the single-crystal scale to the polycrystal meso-scale and the second level employs an implicit finite elements (FE) approach to relate meso scale to macro-scale.
Journal ArticleDOI
Modeling bending of α-titanium with embedded polycrystal plasticity in implicit finite elements
Marko Knezevic,Ricardo A. Lebensohn,Oana Cazacu,Benoit Revil-Baudard,Gwénaëlle Proust,Sven C. Vogel,Michael E. Nixon +6 more
TL;DR: In this article, a polycrystal self-consistent model embedded in finite elements is used to simulate deformation of textured α-titanium under quasi-static conditions at room temperature.
Journal ArticleDOI
Three dimensional predictions of grain scale plasticity and grain boundaries using crystal plasticity finite element models
TL;DR: In this paper, the authors use crystal plasticity finite element (CPFE) models of 2D and 3D polycrystalline microstructures to elucidate 3D topological effects on microstructural evolution during rolling deformation.
