NAFEMS Webinar: Physics, Uncertainty & Scale

Modern aircraft certification relies heavily on costly, time-consuming physical testing. Yet, the escalating complexity of nonlinear, failure-driven behaviour in large composite assemblies demands a new paradigm. With Airbus expertise in-tandem, & rooted in my ongoing doctoral advising for their engineer Rahul’s research on uncertainty quantification, this talk dives deep into cutting-edge advances: from the principled deployment of the Variational Asymptotic Method (VAM) & the collateral model order reduction to the latest adaptive sampling, dimensionality reduction, & multi-fidelity frameworks. The session will examine how projection-based & physics-informed strategies can distil multi-million degree-of-freedom nonlinear finite element (FE) models, retaining essential behavioural fidelity, yet rendering uncertainty analysis truly tractable & reasonably meaningful!
