Irradiation-Driven Recrystallization in Fusion-Grade Tungsten: A Mesoscale, Microstructure-Aware Model
Jinxin Yu, Sicong He, Giacomo Po +3
Tungsten (W) is the leading candidate material for plasma-facing components in fusion reactors, yet its upper operational temperature is limited by premature grain growth and recry…
Data-mining of dislocation microstructures: concepts for coarse-graining of internal energies
Hengxu Song, Nina Gunkelmann, Giacomo Po +1
Continuum models of dislocation plasticity require constitutive closure assumptions, e.g., by relating details of the dislocation microstructure to energy densities. Currently, the…
Inference and Prediction of Nanoindentation Response in FCC Crystals: Methods and Discrete Dislocation Simulation Examples
Michail Tzimas, John Michopoulos, Giacomo Po +2
Nanoindentation, a common technique for probing the mechanical properties of crystalline materials, exhibits both surface and bulk-dominated responses that are linked to the parent…
The Green tensor of Mindlin's anisotropic first strain gradient elasticity
Giacomo Po, Nikhil Chandra Admal, Markus Lazar
We derive the Green tensor of Mindlin's anisotropic first strain gradient elasticity. The Green tensor is valid for arbitrary anisotropic materials, with up to 21 elastic constants…
A unified framework for polycrystal plasticity with grain boundary evolution
Nikhil Chandra Admal, Giacomo Po, Jaime Marian
Plastic deformation in polycrystals is governed by the interplay between intra-granular slip and grain boundary-mediated plasticity. However, while the role played by bulk dislocat…
A non-singular theory of dislocations in anisotropic crystals
Giacomo Po, Markus Lazar, Nikhil Chandra Admal +1
We develop a non-singular theory of three-dimensional dislocation loops in a particular version of Mindlin's anisotropic gradient elasticity with up to six length scale parameters.…
