Analysis of the strain transfer in a new FBG sensor for Structural Health Monitoring

Torres Górriz, Benjamín; Paya-Zaforteza, I.; Calderón García, Pedro Antonio; Adam Martínez, José Miguel (Elsevier, 2011-02)

Structural Health Monitoring (SHM) is a topic of great interest in structural engineering due to the ageing of the built infrastructures and the growing use of innovative structural systems and construction materials. ...
Assessment of Fiber Bragg Grating Sensors for Monitoring Shaft Vibrations of Hydraulic Turbines

Sánchez-Botello, Xavier; Roig, Rafael; De La Torre, Oscar; Madrigal-Madrigal, Javier; Sales Maicas, Salvador; Escaler, Xavier (MDPI AG, 2023-08)

[EN] The structural dynamic response of hydraulic turbines needs to be continuously monitored to predict incipient failures and avoid catastrophic breakdowns. Current methods based on traditional off-board vibration sensors ...
Comparison of numerical and experimental strain distributions in composite panel for aerospace applications

Mucha, Waldemar; Kuś, Wacław; Viana, Júlio; Nunes, João (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] In structural applications of aerospace industry, weight efficiency, understood as minimal weight and maximal stiffness, is of great importance. This criterion can be achieved by composite lightweight structures. ...
Experimental and numerical analysis of a hybrid FBG long gauge sensor for structural health monitoring

Torres Górriz, Benjamín; Calderón García, Pedro Antonio; Paya-Zaforteza, Ignacio; Sales Maicas, Salvador (IOP Publishing: Hybrid Open Access, 2014-10-29)

This paper presents a new long gauge sensor for structural health monitoring based on the use of Fiber Bragg gratings. The proposed sensor has the advantage over existing sensors that it does not require prestressing of ...
Influence of mechanical and geometrical properties of embedded long-gauge strain sensors on the accuracy of strain measurement

Calderón García, Pedro Antonio; Glisic, B. (IOP Publishing: Hybrid Open Access, 2012-04-30)

In many civil and geotechnical applications it is of interest to monitor the strain deep inside the structure; consequently, it is necessary to embed the sensors into the structure's material. Construction and geotechnical ...
Largely tunable dispersion chirped polymer FBG

Min, Rui; Korganbayev, Sanzhar; Molardi, Carlo; Broadway, Christian; Hu, Xuehao; Caucheteur, Christophe; Bang, Ole; Antunes, Paulo; Tosi, Daniele; Marques, Carlos; Ortega Tamarit, Beatriz (The Optical Society, 2018-10-15)

[EN] We demonstrate a largely tunable dispersion fiber Bragg grating (FBG) inscribed in a microstructured polymer optical fiber (mPOF). The bandwidth of the chirped FBG (CFBG) was achieved from 0.11 to 4.86 nm, which ...
