Structural Health Monitoring Using Embedded Fiber Optic Strain Sensors, Rodrigo Silva Muñoz
Structural Health Monitoring Using Embedded Fiber Optic Strain Sensors, Rodrigo Silva Muñoz
Electronic Theses and Dissertations
This dissertation involved several research activities with the common goal of developing a structural health monitoring methodology. The research activities encompass: composites fabrication, numerical modeling and a mechanical experimental program using a state-of-the-art sensing technology. The first part of the dissertation presents an analytical and experimental effort to characterize the bending response of sandwich composite plates. A general expression for the shear correction factor for laminated plates was derived using the principle of strain energy equivalence. It was proved that the first-order shear deformation theory (FSDT) can be confidently used in the elastic analysis of sandwich composite plates with lowdensity …
A Durability And Utility Analysis Of Efpi Fiber Optic Strain Sensors Embedded In Composite Materials For Structural Health Monitoring, Adam Benjamin Haskell
A Durability And Utility Analysis Of Efpi Fiber Optic Strain Sensors Embedded In Composite Materials For Structural Health Monitoring, Adam Benjamin Haskell
Electronic Theses and Dissertations
The objective of the research work was to develop a method to embed fiber optic sensors (FOS) that measure strain in polymer matrix composite (PMC) laminates and sandwich composite panels, to apply the technology to structural health monitoring, and to assess the durability of the sensor system through a fatigue test protocol applied to sandwich composite panels. There is a growing interest in determining and monitoring the performance and sustainability of structures such as bridges, buildings, marine vessels, and aerospace structures. By monitoring structural elements, damage to the structure can be detected resulting in more efficient repair and maintenance schedules, …
