Effects of grain size and boundary structure on the dynamic tensile response of copper
Juan P. Escobedo,Darcie Dennis-Koller,Ellen K. Cerreta,Brian M. Patterson,Curt A. Bronkhorst,Benjamin L Hansen,Davis L. Tonks,Ricardo A. Lebensohn +7 more
TL;DR: In this paper, the influence of grain boundary characteristics on the dynamic tensile response of Cu samples with grain sizes of 30, 60, 100, and 200 μm was examined using optical and electron microscopy along with micro x-ray tomography.

Journal ArticleDOI
Quantitative analysis of deformation twinning in zirconium
TL;DR: In this paper, electron backscatter diffraction (EBSD) was used to quantify the contributions of first generation and second generation twinning to the total plastic strain of zirconium compressed at 76 K.
Journal ArticleDOI
An experimental and numerical study of the localization behavior of tantalum and stainless steel
TL;DR: In this article, the deformation response of stainless steel and tantalum samples was modeled using an anisotropic elasto-viscoplastic constitutive model within the finite element code EPIC.
Journal ArticleDOI
A dislocation-based multi-rate single crystal plasticity model
TL;DR: In this paper, an elastic-viscoplastic, slip-based single crystal model that accounts for crystallographic orientation, temperature, and strain rate dependence has been formulated based on dislocation dynamics simulations and existing experimental data.
