The engineering of composite aircraft structures relies heavily on Finite Element Models (FEMs) to predict the structural response, stresses, and fatigue life due to static and dynamic loads. The creation of accurate models requires experimental measurement of load distribution and resultant structural deflections/strains. The solution proposed for large area full-field strain measurement calls for the integration of technologies in laser-based and optical-based metrology. The proposed approach will allow for real-time data capture and analysis of critical areas at variable data acquisition rates.
