Defect-based Physics-Informed Machine Learning Framework for Fatigue Prediction

I would like to draw your attention to our recently proposed predictive method based on a semi-empirical model (LEFM) and Neural Network, exploiting the Physics-informed Machine Learning concept. We show how the accuracy of state-of-the-art fatigue predictive models, based on defects present in materials, can be significantly boosted by accounting for additional morphological features via Physics-Informed Machine Learning. Although defect-based methodologies are widely employed in additively manufactured materials in these days, the methods can be effectively employed to other problems dealing with metallic materials presenting defects. I believe this is the way to go for the identification and quantification of “hidden” fatigue influencing factors while ensuring the soundness of the prediction.
