Fibre Bragg grating sensor applications for structural health monitoring
Karatas, Cansu; Degerliyurt, Boray; Yaman, Yavuz; Şahin, Melin (Emerald, 2018-12-01)
Purpose
Extended Abstract: Dynamic Behavior of a Compliant Mechanism Driven by Stacked Piezoelectric Actuators
Koyuncu, A.; Şahin, Melin; Özgüven, Hasan Nevzat (2018-02-15)
Mechanical amplifiers are employed to enhance output displacement of piezoelectric actuators. Dynamic behavior of such an amplified piezoelectric actuator needs to be known accurately in order to verify its suitability for...
Active neuro-adaptive vibration suppression of a smart beam
Akin, Onur; Şahin, Melin (2017-12-01)
In this research, an active vibration suppression of a smart beam having piezoelectric sensor and actuators is investigated by designing separate controllers comprising a linear quadratic regulator and a neural network. Fi...
Enhancement of quality of modal test results of an unmanned aerial vehicle wing by implementing a multi-objective genetic algorithm optimization
Pedramasl, Nima; Şahin, Melin; ACAR, ERDEM (2017-12-01)
Due the fact that aircraft structures work in an environment with lots of dynamic forces, it is of vital importance to perform a dynamic analysis to understand dynamic characteristics of aircraft in that specific environme...
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 o...
Structural and aerodynamic analyses of a hybrid trailing edge control surface of a fully morphing wing
Gürses, Ercan; Tunçöz, Ilhan Ozan; Yang, Yosheph; Arslan, Pinar; Kalkan, Ugur; Tıraş, Harun; Şahin, Melin; Özgen, Serkan; Yaman, Yavuz (2017-05-01)
In this article, the design and analysis of a hybrid trailing edge control surface of an unmanned aerial vehicle are presented. The structural design was performed to increase and decrease the camber of the control surface...
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 int...
Bimorph piezoelectric energy harvester structurally integrated on a trapezoidal plate
Avsar, Ahmet Levent; Şahin, Melin (2016-08-01)
A bimorph piezoelectric energy harvester is developed for harvesting energy under the vortex induced vibration and it is integrated to a host structure of a trapezoidal plate without changing its passive dynamic properties...
Modal Analyses and Experimental Verifications of Joined-Wing Configurations
Alanbay, Berkan; Şahin, Melin; Canbaloglu, Guvenc (2016-01-28)
In recent days, wing kits are extensively used to convert conventional munitions into guided munitions. The wing kit integration enables munitions to gain standoff attack capability, extends their range and together with a...
Decamber Morphing Concepts by Using a Hybrid Trailing Edge Control Surface
Yaman, Yavuz; Tuncoz, Ilhan Ozan; Yang, Yosheph; Arslan, Pinar; Kalkan, Ugur; Tiras, Harun; Gürses, Ercan; Şahin, Melin; Özgen, Serkan (2015-09-01)
The idea of morphing is drawing extensive attention in aerospace technologies. Several different approaches like span, camber, twist, and sweep are finding applications. In this work, the concept of a trailing edge control...
