Methodology for modeling damaged beams with geometric and structural variation

Author

David Anthony Comella

Abstract

"Inaccuracies in the modeling assumptions about the distributional characteristics of the monitored signatures have been shown to cause frequent false positives in vehicle monitoring systems for high-risk aerospace applications. To enable the development of robust fault detection methods, this thesis explores the deterministic as well as variational characteristics of failure signatures. Specifically, it explores the combined impact of crack damage and manufacturing variation on the vibrational characteristics of beams, which has received little attention in the literature."--Abstract, page iii.
