Structural fault detection using fuzzy logic

This paper presents a general methodology for structural fault detection using fuzzy logic. The methodology is based on monitoring the static, eigenvalue, and dynamic responses to determine the health status of a structure or machine. Fuzzy logic coupled with principles of continuum damage mechanics is used to identify the location and extent of the damage. The proposed methodology represents a unique approach to damage detection that can be applied to a variety of structures used in civil-engineering, machine, and aerospace applications. (Author)
