Strain measurement of hydraulic turbine using distributed optical fiber sensor: a preliminary study
Luc Thévenaz, Can Yao, Pingyu Zhu
This paper demonstrates the feasibility and huge potential of applying distributed fiber optic sensing technologies to strain monitoring and failure predictions in hydraulic machinery, validated by a good match between experimental results and theoretical ...
Optical Society of America, 20202020Distributed modular temperature-strain sensor based on optical fiber embedded in laminated composites
Marcelo Alfonso Soto Hernandez, Pingyu Zhu
A smart structure based on carbon fiber reinforced polymer (CFRP) embedding optical fibers is proposed for distributed sensing in structural health monitoring. The proposed CFRP package provides mechanical protection to the optical fiber, enables temperatu ...
2018Preliminary Study of Distributed Fiber Optic Sensing Technologies in Hydraulic Machinery
Luc Thévenaz, Camille Sophie Brès, Can Yao, Xiaopeng Huang, Pingyu Zhu
This paper includes a preliminary study of bringing innovative and promising distributed optical fiber sensing technologies to strain monitoring of hydraulic machinery. ...
Optical Society of America2018Delamination monitoring using low frequency stress waves for laminated composites
Wei Shi, Zhisheng Yang, Pingyu Zhu
Owing to the anisotropy of composite laminates, local responses happens at periphery of the drilled hole even under the same loads. The strain measurement is probably the most sensitive and better option to detect and quantify delamination inside composite ...
Politecnico di Milano2016Seepage and settlement monitoring for earth embankment dams using fully distributed sensing along optical fibers
Luc Thévenaz, Yao Zhou, Pingyu Zhu
A method for seepage and settlement monitoring in earth embankment dams using fully distributed sensing along optical fibres is proposed. A model is developed for simulating and monitoring seepage and settlement systems. This model relates the strains and ...
SPIE2008Design of simulator for seepage detection in an embankment based on distributed optic fibre sensing technology
Luc Thévenaz, Pingyu Zhu, Yang Zhou
Based on the temperature change in an embankment, a seepage flow simulator and monitoring system based on distributed optical fiber sensing are proposed. A simulator is designed that consists of scale model of embankment with definite length, seepage flow ...
