We propose a novel deep reinforcement learning (DRL)-based prognostic method. Our approach integrates Denoising Autoencoder (DAE) and Transformer architectures to construct a powerful DRL Policy Network, capable of extracting high-quality features from X-ray records to capture the subtle progression of damage in CFRP structures.

This paper proposes a physics-guided deep learning framework to integrate physics into data-driven models. This physics-guided convolutional neural network leverages structural degradation trend and physical consistency by combining the output of the physical model with the observed feature in a hybrid model. This hybrid model uses an additional branch to observe the information of stiffness degradation, which is the input into the physical model to describe the damage growth in structures by establishing a relationship with the power spectral density change in the guided wave signals.

This study proposes a deep transfer learning-based model, called MDAAN, for the damage detection of CFRP composite structures. MDAAN learns the physical mechanism of fatigue damage from the simulation data generated by the finite element model, and can then transfer this knowledge to real-world experimental data to detect and locate the fatigue damage.
