In this work, an experimental methodology is proposed to determine the statistical correlation between mechanical properties of unidirectional FRP composite. A rectangular shaped carbon fiber reinforced plastic (CFRP) specimen with a circular hole is loaded by tension, and 3D digital image correlation (DIC) is employed to characterize the heterogeneous strain field around the hole. Virtual field method (VFM) is used to derive E11, E22, \u03bd12, and G12 of specimens. Specimen configuration considering fiber angle and hole diameter is optimized to achieve accurate determination of correlation coefficients. Experimental results on the linear correlation coefficients between E11, E22, \u03bd12, and G12 agree well with previous theoretical predictions.<\/jats:p>","DOI":"10.3390\/ma13030674","type":"journal-article","created":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T11:28:31Z","timestamp":1580729311000},"page":"674","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Experimental Identification of Statistical Correlation between Mechanical Properties of FRP Composite"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9252-2986","authenticated-orcid":false,"given":"Shufeng","family":"Zhang","sequence":"first","affiliation":[{"name":"Science and Technology on Integrated Logistics Support Laboratory, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tongzhen","family":"Xing","sequence":"additional","affiliation":[{"name":"School of Aerospace Engineering, Beijing Institute of Technology, Beijing 100811, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haibin","family":"Zhu","sequence":"additional","affiliation":[{"name":"Flexible Optical Measurement and Technology Centre, Institute of Flexible Electronics Technology of Tsinghua University, Jiaxing 314000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xun","family":"Chen","sequence":"additional","affiliation":[{"name":"Science and Technology on Integrated Logistics Support Laboratory, National University of Defense Technology, Changsha 410073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"219","DOI":"10.1016\/S0045-7949(99)00171-6","article-title":"Probabilistic strength analysis of rectangular frp plates using monte carlo simulation","volume":"76","author":"Jeong","year":"2000","journal-title":"Comput.
