Abstract

Modern engineering structures form complex  - often interconnected - assemblies that operate under highly varying loads and adverse environments. To ensure a resource-efficient and resilient operation of such systems, it is imperative to understand their performance as-is; a task which can be effectuated through Structural Health Monitoring (SHM). Structural Health Monitoring comprises a hierarchy across levels of increasing complexity aiming to i) detect, ii) localize and iii) quantify damage, and iv) finally offer a prognosis over the system's residual life. When considering higher levels in this hierarchy, including damage assessment and even performance prognosis, purely data-driven methods are found to be lacking. For higher-level SHM tasks, or for furnishing a digital twin of a monitored structure, it is necessary to i) integrate knowledge stemming from physics-based representations, and ii) assimilate experience garnered from expert operators. This talk discusses implementation of such a hybrid approach to treating cyber physical systems for tackling the aforementioned challenges and improving our oversight on the operation of critical systems and structures. We offer a view to establishing augmented twin representations, capable of representing the structure as-is, anticipating performance under future stressors, and advising on preventive and remedial actions.
