Technics for damage and fatigue detection has become an essential part of
Aeronautic industry safety. The duration of service lives of such vehicles can be considerably extended by systematic monitoring of small, possibly undetected, damages to their structures. In this paper, we propose damage detection in airplane structures via modal analysis. By using Finite Element Method numerical models, developed in commercial software, as a first step, we make comparisons of the free vibration frequencies of undamaged models and models where we deliberately introduce damage. We observe the difference in frequency values. In future work we will propose numerical damage indicators based on the modal analysis.
Keywords: Aeronautical Structure, Damage Detection, Modal Analysis, FEM.
