Variational Neural Network Embedded with Digital Twins for Probabilistic Structural Damage Quantification

Jiaqi Xu,
Xuan Zhou,
Marco Giglio
et al.

Abstract: Quantifying structural damage using online monitoring data is crucial for condition-based maintenance to ensure aviation safety. However, most data-driven methods hardly use accumulated domain knowledge, making it difficult to address parameter variability across different structures due to manufacturing as well as compromising result interpretability. To address these challenges, this study proposes a physics-decoded variational neural network for structural damage quantification and model parameter calibrati… Show more
