Manifold learning for coarse-graining atomistic simulations: Application to amorphous solids
Katiana Kontolati, Darius Alix-Williams, Nicholas M. Boffi +3
We introduce a generalized machine learning framework to probabilistically parameterize upper-scale models in the form of nonlinear PDEs consistent with a continuum theory, based o…

Shear Band Broadening in Simulated Glasses
Darius D. Alix-Williams, Michael L. Falk
Two models are proposed to predict the evolution of shear band width as a function of applied strain for simulated glasses mechanically deformed in simple shear. The first model ar…
