Abstract Scope |
Void nucleation and growth in polycrystalline metals during spall is a complex phenomenon that is not fully understood. This study employs machine learning and phase field modeling to study incipient spall under high-impact dynamic loading conditions. We develop a machine learning model designed to predict potential void nucleation sites in polycrystalline metal microstructures. Validation is performed across various microstructural datasets and synthetic microstructures generated using Generative Adversarial Networks.
The machine learning model is used to generate heatmaps that act as void nucleation probability fields, which informs a phase field damage model. The phase field model, based on the minimum dissipation potential, simulates void nucleation and growth due to incipient spall under high-impact dynamic loading conditions, taking into account chemical potential, grain boundary energy, elasticity, and plastic potential.The integration of machine learning predictions with phase field modeling enables accurate simulation of void evolution, demonstrating strong concordance with experimental observations. |
