Mechanics of incompatible asymmetric grain boundary migration
Brandon Runnels
Grain boundary (GB) migration governs microstructure evolution and can mediate plastic deformation through sliding or shear coupling. Numerous experimental and numerical studies ha…
Predicting void nucleation in microstructure with convolutional neural networks
Abhijith Thoopul Anantharanga, Jackson Plummer, Saryu Fensin +1
Void nucleation in ductile materials subjected to high strain-rate loading remains a critical yet elusive phenomenon to understand. Traditional methods to understand void nucleatio…
The structure and migration of twin boundaries in tetragonal -Sn: an application of machine learning based interatomic potentials
Ian Chesser, Mashroor Nitol, Esther C. Hessong +7
Although atomistic simulations have contributed significantly to our understanding of twin boundary structure and migration in metals and alloys with hexagonal close packed (HCP) c…
Energetics of the nucleation and glide of disconnection modes in symmetric tilt grain boundaries
Himanshu Joshi, Ian Chesser, Brandon Runnels +1
GBs evolve by the nucleation and glide of disconnections, which are dislocations with a step character. In this work, motivated by recent success in predicting GB properties such a…
Grain boundary network plasticity: reduced-order modeling of deformation-driven microstructure evolution
Daniel Bugas, Brandon Runnels
Microstructural evolution in structural materials is known to occur in response to mechanical loading and can often accommodate substantial plastic deformation through the coupled…
A taxonomy of grain boundary migration mechanisms via displacement texture characterization
Ian Chesser, Brandon Runnels, Elizabeth Holm
Atomistic simulations provide the most detailed picture of grain boundary (GB) migration currently available. Nevertheless, extracting unit mechanisms from atomistic simulation dat…
Multiphase field modeling of grain boundary migration mediated by emergent disconnections
Mahi Gokuli, Brandon Runnels
Knowledge about grain boundary migration is a prerequisite for understanding and ultimately modulating the properties of polycrystalline materials. Evidence from experiments and mo…
