Abstract Scope |
Crystal deformation simulations are a powerful tool for analyzing the anisotropic behavior of microstructures. A generalizable graph neural network (GNN) framework’s efficacy as a surrogate is evaluated for modeling the evolution of microstructural phenomena. Commonly, finite element analysis (FEA) and spectral methods have been used to model deformation mechanisms, but they can be limited by high computational demand and simple deformation modes respectively. We explore training a deep-learning based GNN model on both 2D and 3D finite-element crystal elasticity data. Our model achieves good accuracy on held out datasets, extrapolates well to larger systems, and is faster than conventional methods. |
