Equivariant graph neural network surrogates for predicting the properties of relaxed atomic configurations
Jamie Holber, Siddhartha Srivastava, Krishna Garikipati
Density functional theory (DFT) calculations determine the relaxed atomic positions and lattice parameters that minimize the formation energy of a structure. We present an equivari…

Inference of phase field fracture models
Elizabeth Livingston, Siddhartha Srivastava, Jamie Holber +2
The phase field approach to modeling fracture uses a diffuse damage field to represent a crack. This addresses the singularities that arise at the crack tip in computations with sh…
