Fiber Bragg Grating sensors are commonly being used for Structural Health Monitoring of aeronautical structures. Fiber Bragg Grating sensors are convenient especially for Structural Health Monitoring of composite structures, such as helicopter blades and wind turbine blades, considering the ability of embedment between the layers. In this study, a Structural Health Monitoring system of composite beams equipped with surface bonded and embedded Fiber Bragg Grating sensors is introduced. Torsion tests of the composite beams are conducted to observe the performance of the system by monitoring the torque and shear strain. Validation of the test results are achieved by comparing the results obtained from the Finite Element Analyses and the performed tests. In addition, manufacturing methods and precautions to avoid plausible harms to the sensors are presented.

Structural Health Monitoring system of composite beams with surface bonded and embedded Fibre Bragg Grating sensors
Deǧerliyurt, Boray; Karataş, Cansu; Şahin, Melin; Yaman, Yavuz (2017-01-15)
Fibre Bragg Grating (FBG) sensors are frequently being used for Structural Health Monitoring (SHM) of aerospace structures. One of the most important advantages of using FBG sensors is that it is possible to embed them into composites. In this paper, manufacturing methods of composite specimens with embedded FBG sensors are given. To avoid stress concentrations at ingress/egress regions of fibre optic wires, PTFE (Teflon) tubes were used during manufacturing. Moreover, FBG connectors melt at high curing tem...
Finite element analysis and tests of composite beams with fiber bragg grating sensors under torsional load for structural health monitoring applications
Karataş, Cansu; Yaman, Yavuz; Department of Aerospace Engineering (2017)
In this thesis, feasibility of Fiber Bragg Grating sensors for Structural Health Monitoring applications of composite structures is studied. The method and essentials for the manufacturing process of composite beams with embedded Fiber Bragg Grating sensors are presented. Composite beams instrumented with surface bonded and embedded Fiber Bragg Grating sensors are tested under static torsional load. In addition, Finite Element Analyses of composite beams under torsional load is conducted using the commercia...
Active vibration control of beams and cylindrical structures using piezoelectric patches
Gençoğlu, Caner; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2014)
Airborne structures are required to be lightweight in today's designs. However this lowers the overall stiffness of the structure and causes low frequency vibration problems for which passive vibration control techniques are inadequate. Active vibration control using piezoelectric patches is a promising technology to solve vibration problems of aerospace structures. Many studies were done on beam and plate geometries, however studies on cylinder geometry which is used extensively as engineering structure, i...
Cable axial load measurement device and buckling sensor development
Usalan, Emine Ceren; Türer, Ahmet; Department of Civil Engineering (2015)
Axial compression or tension carrying members may need to be monitored for their structural behaviors and/or damage detection. In this thesis, two different types of practical and cost efficient monitoring devices are proposed: The column buckling sensor and the cable tension measuring device. The columns of steel structures are prone to buckling due to their slender nature. The buckling sensor is developed by using strain gauges installed in half Wheatstone bridge and measures the strain level of the most ...
FIBER BRAGG GRATING SENSOR APPLICATIONS FOR STRUCTURAL HEALTH MONITORING
Karataş, Cansu; Değerliyurt, Boray; Yaman, Yavuz; Şahin, Melin (2017-09-30)
A well-known structural health monitoring method used to detect and locate damage in civil engineering structures is vibration-based damage identification. It typically monitors the civil structure over time to spot slow or sudden changes in its natural frequencies, damping factors or modal displacements. This approach can prove very powerful, but the sensitivity of those properties to local damage can be rather low. In addition, their cross-sensitivity to environmental influences may completely mask the ef...
