Abstract Scope |
Fatigue cracks spend the majority of their lifetime when they are microstructurally small. Predicting microstructurally small crack (MSC) behavior early on can significantly benefit damage prognosis and maintenance. However, MSCs are influenced by the local microstructure, rendering the prediction of their growth behavior a challenge by both experimental and numerical tools. We propose a framework for rapid prediction of this complex spatiotemporal behavior of MSCs using deep learning. In this work, we train three state-of-the-art deep learning models, namely convolutional neural networks, graph convolutional networks, and transformers, and compare their performance in predicting MSC growth characteristics. The training data for these models are acquired from a large number of “virtual” MSC growth observations enabled by high-fidelity finite-element-based simulations. The unique data processing strategies, deep learning model development, and model performance comparisons will be presented, and the model’s generalization ability will be demonstrated. |
