The delta-T mapping technique developed by researchers has been shown to enable AE source location to a high level of accuracy in complex structures. However, the time-consuming and laborious data training process of the delta-T mapping technique has prevented this technique from large-scale application on large complex structures. In order to solve this problem, a Finite Element (FE) method was applied to model training data for localization of experimental AE events on a complex plate. Firstly, the FE model was validated through demonstrating consistency between simulated data and the experimental data in the study of Hsu-Nielsen (H-N) sources on a simple plate. Then, the FE model with the same parameters was applied to a planar location problem on a complex plate. It has been demonstrated that FE generated delta-T mapping data can achieve a reasonable degree of source location accuracy with an average error of 3.88 mm whilst decreasing the time and effort required for manually collecting and processing the training data.<\/jats:p>","DOI":"10.3390\/s22072493","type":"journal-article","created":{"date-parts":[[2022,3,24]],"date-time":"2022-03-24T23:31:43Z","timestamp":1648164703000},"page":"2493","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Acoustic Emission Source Location Using Finite Element Generated Delta-T Mapping"],"prefix":"10.3390","volume":"22","author":[{"given":"Han","family":"Yang","sequence":"first","affiliation":[{"name":"TWI Ltd., Granta Park, Great Abington, Cambridge CB21 6AL, UK"},{"name":"Department of Mechanical and Aerospace Engineering, Brunel University London, Uxbridge UB8 3PH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1398-6599","authenticated-orcid":false,"given":"Bin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering, Brunel University London, Uxbridge UB8 3PH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Grigg","sequence":"additional","affiliation":[{"name":"TWI Ltd., Granta Park, Great Abington, Cambridge CB21 6AL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Zhu","sequence":"additional","affiliation":[{"name":"Key Laboratory of High Performance Ship Technology (Wuhan University of Technology), Ministry of Education, Wuhan 430063, China"},{"name":"School of Naval Architecture, Ocean and Energy Power Engineering, Wuhan University of Technology, Wuhan 430063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dandan","family":"Liu","sequence":"additional","affiliation":[{"name":"TWI Ltd., Granta Park, Great Abington, Cambridge CB21 6AL, UK"},{"name":"Department of Mechanical and Aerospace Engineering, Brunel University London, Uxbridge UB8 3PH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Marks","sequence":"additional","affiliation":[{"name":"TWI Ltd., Granta Park, Great Abington, Cambridge CB21 6AL, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"F4016001","DOI":"10.1061\/(ASCE)ST.1943-541X.0001544","article-title":"Life-cycle performance of deteriorating structural systems under uncertainty","volume":"142","author":"Biondini","year":"2016","journal-title":"J.
