Grain boundary metastability controls irradiation resistance in nanocrystalline metals
Osman El-Atwani, Annie K. Barnett, Enrique Martinez +13
Grain boundaries (GBs) in polycrystalline materials are powerful sinks for irradiation defects. While standard theories assume that the sink efficiency of a grain boundary is defin…
Data-Driven Modeling of Dislocation Mobility from Atomistics using Physics-Informed Machine Learning
Yifeng Tian, Soumendu Bagchi, Liam Myhill +5
Dislocation mobility, which dictates the response of dislocations to an applied stress, is a fundamental property of crystalline materials that governs the evolution of plastic def…
Stochastic Integration of the Cahn-Hilliard Phase Field Equations
Qianran Yu, Nicholas Julian, Jaime Marian +1
In this work we develop a stochastic algorithm to integrate the Cahn-Hilliard equations. The algorithm is based on Gillespie's stochastic simulation algorithm, also known as kineti…
From anti-Arrhenius to Arrhenius behavior in a dislocation-obstacle bypass: Atomistic Simulations and Theoretical Investigation
Mohammadhossein Nahavandian, Soumit Sarkar, Soumendu Bagchi +2
Dislocations are the primary carriers of plasticity in metallic material. Understanding the basic mechanisms for dislocation movement is paramount to predicting the material mechan…
