Abstract:

In the context of long-term monitoring applications, there are numerous structural states that exhibit similar behaviour but cannot be generalised with a single model (whether data- or physics-based) due to the inherent time-variant nature of structural evolution. Addressing such scenarios necessitates methodologies with adaptable models that can capture the interdependencies between Environ-mental and Operational Variabilities (EOV) and Damage Sensitivity Features (DSF) at various stages of structural evolution. The challenge lies in determining when distinct structures can be considered pseudo-similar, thereby sharing the same underlying physical properties to better represent the dynamics and associated EOV dependencies. Similarly, the incorporation of physics-based models, with varying levels of fidelity, adds knowledge towards understanding structural changes, which is essential for incorporating interpretable constraints on DSF evolution. In this seminar, I aim to share recent advances from the Dynamics, Vibration and Monitoring research group on two fronts: (i) the latest approaches for mitigating the effects of EOV through adaptive stochastic data modelling that evolves with the structural integrity, and (ii) the capabilities of incorporating underlying physics models of the dynamics of structural elements to inform real data through interpretable constraints and predictions on structural integrity evolution. The fundamentals of theseapproaches and their applications in the wind energy sector will be presented.
