Investigation of ideal shear strength of dilute binary and ternary Ni-based alloys using first-principles calculations, CALPHAD modeling and correlation analysis

Autor: Lin, Shuang, Shang, Shun-Li, Shimanek, John D., Wang, Yi, Beese, Allison M., Liu, Zi-Kui

In the present work, the ideal shear strength (Tis) of dilute Ni34XZ ternary alloys (X or Z = Al, Co, Cr, Fe, Mn, Mo, Nb, Si, Ti) are predicted by first-principles calculations based on density functional theory (DFT) in terms of pure alias shear def

Effects of Misorientation on Single Crystal Plasticity by Finite Element Methods

Autor: Shimanek, John D., Liu, Zi-Kui, Beese, Allison M.

Publikováno v: Computational Materials Science 237 (2024) 112879

The crystal plasticity finite element method (CPFEM) is a widely used technique for resolving macroscopic stress and strain onto the physically relevant length scales of grains and slip systems in ductile crystalline materials like structural metals.

Insight into Ideal Shear Strength of Ni-based Dilute Alloys using First-Principles Calculations and Correlational Analysis

Autor: Shimanek, John D., Shang, Shun-Li, Beese, Allison M., Liu, Zi-Kui

Publikováno v: Computational Materials Science 212 (2022) 111564

The present work examines the effect of alloying elements (denoted X) on the ideal shear strength for 26 dilute Ni-based alloys, Ni$_{11}$X, as determined by first-principles calculations of pure alias shear deformations. The variations in ideal shea

Predictive Crystal Plasticity Modeling of Single Crystal Nickel Based on First-Principles Calculations

Autor: Shimanek, John D., Qin, Shipin, Shang, Shun-Li, Liu, Zi-Kui, Beese, Allison M.

Publikováno v: JOM 74 (2022) 1423

To reduce reliance on experimental fitting data within the crystal plasticity finite element method (CPFEM), an approached is proposed that integrates first-principles calculations based on density functional theory (DFT) to predict the strain harden
