"Irregularization" of Systems of Conservation Laws
Hunter Swan, Woosong Choi, Stefanos Papanikolaou +3
We explore new ways of regulating defect behavior in systems of conservation laws. Contrary to usual regularization schemes (such as a vanishing viscosity limit), which attempt to…
Scaling theory of continuum dislocation dynamics in three dimensions: Self-organized fractal pattern formation
Yong S. Chen, Woosong Choi, Stefanos Papanikolaou +2
We focus on mesoscopic dislocation patterning via a continuum dislocation dynamics theory (CDD) in three dimensions (3D). We study three distinct physically motivated dynamics whic…
Is dislocation flow turbulent in deformed crystals?
Woosong Choi, Yong S. Chen, Stefanos Papanikolaou +1
Intriguing analogies were found between a model of plastic deformation in crystals and turbulence in fluids. A study of this model provides remarkable explanations of known experim…
Bending crystals: Emergence of fractal dislocation structures
Yong S. Chen, Woosong Choi, Stefanos Papanikolaou +1
We provide a minimal continuum model for mesoscale plasticity, explaining the cellular dislocation structures observed in deformed crystals. Our dislocation density tensor evolves…
