The degradation of steel structures due to hydrogen embrittlement, driven by hydrogen uptake during cathodic hydrogen evolution reactions, remains a critical issue for material integrity in demanding environments. This study explores a coupled model that links the electrochemical processes of hydrogen generation and absorption with the mechanical degradation mechanisms of embrittlement and plastic deformation, monitored through acoustic emission (AE) techniques. By analyzing AE data alongside mechanical and electrochemical parameters, the model aims to provide a deeper understanding of the interactions between hydrogen-induced damage and mechanical failure in steel. Preliminary findings suggest a strong correlation between hydrogen uptake levels and the onset of embrittlement, with hydrogen accumulation leading to a noticeable reduction in material ductility. Additionally, AE signals appear to capture distinct stages of damage progression, offering potential insights into the transition from hydrogen-induced cracking to plastic deformation. While the model is still under development, early results indicate that AE monitoring could serve as a valuable tool for tracking damage evolution in real time. This work highlights the potential of integrating electrochemical and mechanical approaches to better understand hydrogen-induced failure in steel. By combining experimental data with modeling efforts, the study aims to contribute to improved predictive capabilities for material durability in hydrogen-rich environments. The ongoing research has implications for industries such as energy, transportation, and marine engineering, where hydrogen embrittlement poses significant challenges to structural safety and longevity.
