Beyond Compression: Training Latent Representations for Stable Long-Horizon Rollout in Neural Surrogate Solvers
Andreas E. Robertson, Ashley T. Lenau, John D. Shimanek +5
Latent neural surrogate solvers, or latent dynamics models, accelerate simulations of time-dependent physical systems by evolving a compressed latent space rather than resolving fu…
Effect of Anisotropic Peierls Barrier on the Evolution of Discrete Dislocation Networks in Ni
John D. Shimanek, Darshan Bamney, Laurent Capolungo +2
Over low and intermediate strain rates, plasticity in face centered cubic (FCC) metals is governed by the glide of dislocations, which manifest as complex networks that evolve with…
Investigation of ideal shear strength of dilute binary and ternary Ni-based alloys using first-principles calculations, CALPHAD modeling and correlation analysis
Shuang Lin, Shun-Li Shang, John D. Shimanek +3
In the present work, the ideal shear strength (τ_is) of dilute Ni34XZ ternary alloys (X or Z = Al, Co, Cr, Fe, Mn, Mo, Nb, Si, Ti) are predicted by first-principles calculations ba…
Effects of Misorientation on Single Crystal Plasticity by Finite Element Methods
John D. Shimanek, Zi-Kui Liu, Allison M. Beese
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…
An image-based transfer learning approach for using in situ processing data to predict laser powder bed fusion additively manufactured Ti-6Al-4V mechanical properties
Qixiang Luo, John D. Shimanek, Timothy W. Simpson +1
The mitigation of material defects from additive manufacturing (AM) processes is critical to reliability in their fabricated parts and is enabled by modeling the complex relations…
Insight into Ideal Shear Strength of Ni-based Dilute Alloys using First-Principles Calculations and Correlational Analysis
John D. Shimanek, Shun-Li Shang, Allison M. Beese +1
The present work examines the effect of alloying elements (denoted X) on the ideal shear strength for 26 dilute Ni-based alloys, NiX, as determined by first-principles calcu…
Predictive Crystal Plasticity Modeling of Single Crystal Nickel Based on First-Principles Calculations
John D. Shimanek, Shipin Qin, Shun-Li Shang +2
To reduce reliance on experimental fitting data within the crystal plasticity finite element method (CPFEM), an approached is proposed that integrates first-principles calculations…
