However, the impact of the monitored structure\u2019s strain distribution on the strain transfer mechanism in DFO sensors has often been overlooked in the existing research. To address this issue, a strain transfer model of surface-bonded DFO sensors with multilayered structures was established based on the shear lag theory. The closed-form solutions of the strain transfer coefficient of DFO sensors subjected to uniform, parabolic, single-linear gradient, and bilinear gradient strains were obtained. With a high-accuracy optical frequency-domain reflectometer (OFDR), the theoretical model was validated by laboratory tests. Upon parametric analysis, suggestions were further offered about designing and installing DFO sensors.<\/jats:p>","DOI":"10.3390\/s23156863","type":"journal-article","created":{"date-parts":[[2023,8,2]],"date-time":"2023-08-02T11:17:17Z","timestamp":1690975037000},"page":"6863","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Strain Transfer Mechanism in Surface-Bonded Distributed Fiber Optic Sensors under Different Strain Fields"],"prefix":"10.3390","volume":"23","author":[{"given":"Wenbo","family":"Du","sequence":"first","affiliation":[{"name":"POWERCHINA Huadong Engineering Corporation Limited, Hangzhou 311122, China"},{"name":"College of Engineering, Ocean University of China, Qingdao 266100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xing","family":"Zheng","sequence":"additional","affiliation":[{"name":"POWERCHINA Huadong Engineering Corporation Limited, Hangzhou 311122, China"},{"name":"Zhejiang Huadong Geotechnical Investigation & Design Institute Corporation Limited, Hangzhou 310030, China"},{"name":"School of Earth Sciences and Engineering, Nanjing University, Nanjing 210046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Earth Sciences and Engineering, Nanjing University, Nanjing 210046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengya","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Earth Sciences and Engineering, Hohai University, Nanjing 211000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"Zhejiang Huadong Geotechnical Investigation & Design Institute Corporation Limited, Hangzhou 310030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weida","family":"Ni","sequence":"additional","affiliation":[{"name":"POWERCHINA Huadong Engineering Corporation Limited, Hangzhou 311122, China"},{"name":"Zhejiang Huadong Geotechnical Investigation & Design Institute Corporation Limited, Hangzhou 310030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenming","family":"Zheng","sequence":"additional","affiliation":[{"name":"Zhejiang Huadong Geotechnical Investigation & Design Institute Corporation Limited, Hangzhou 310030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meifeng","family":"Niu","sequence":"additional","affiliation":[{"name":"Zhejiang Huadong Geotechnical Investigation & Design Institute Corporation Limited, Hangzhou 310030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8601","DOI":"10.3390\/s120708601","article-title":"Recent Progress in Distributed Fiber Optic Sensors","volume":"12","author":"Bao","year":"2012","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1647","DOI":"10.1016\/j.engstruct.2004.05.018","article-title":"Recent applications of fiber optic sensors to health monitoring in civil engineering","volume":"26","author":"Li","year":"2004","journal-title":"Eng.
