Abstract Scope |
Crystal deformation simulations offer a robust means of examining the anisotropic response of microstructures. This study evaluates the effectiveness of a versatile graph neural network (GNN) framework as a surrogate for capturing the dynamic evolution of microstructural phenomena. Traditional methods such as finite element analysis (FEA) and spectral methods have historically been applied to model deformation mechanisms, but they are often hindered by high computational demands and oversimplified deformation modes. In this investigation, we explore the training of a deep-learning-based GNN model using both 2D and 3D finite-element crystal elasticity data. Our model demonstrates commendable accuracy on unseen datasets, reliably extrapolates to larger systems, and the shows the potential to surpass traditional methods in terms of computational efficiency. |
