A non-intrusive adaptive strategy to support real-time structural assessment

摘要

Offline/online strategy for data-driven real-time structural assessment problems 1. Non intrusive methodology 2. POD and SOM combined to obtain fast mapping from measurements to capabilities 3. Variable fidelity and complexity of models invoked 4. Permitted choice among different levels of assessment of a damaged structure to meet different requirements and constraints in resource availability Application: Structural assessment of a wing panel 1. Using sparse sensor measurements of strain to infer the coefficients of the failure index POD model 2. The reconstructions of the failure indices are sufficient to obtain a first-cut assessment to support online decision-making.
