The early detection and characterisation of fatigue crack growth remain a crucial challenge. The scope of the present work was to establish filtering and alarm criteria for different crack growth stages by evaluating the recorded signals and their features. The analysis and definition of parametrical limits, and the correlation of their characteristics with the crack, helped to identify approaches to discriminate between noise, initiation, and growth-related signals. Based on these, a filtering criterion was established, to support the identification of the different growth stages and noise with the aim to provide early warnings of potential damage.<\/jats:p>","DOI":"10.3390\/s21155030","type":"journal-article","created":{"date-parts":[[2021,7,25]],"date-time":"2021-07-25T22:07:00Z","timestamp":1627250820000},"page":"5030","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Diagnostic Feature Extraction and Filtering Criterion for Fatigue Crack Growth Using High Frequency Parametrical Analysis"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6518-8214","authenticated-orcid":false,"given":"\u00c1ngela","family":"Angulo","sequence":"first","affiliation":[{"name":"TWI Ltd., Granta Park, Great Abington, Cambridge, Cambridgeshire CB21 6AL, UK"},{"name":"College of Engineering, Design and Physical Sciences, Brunel University London, Kingston Lane, Uxbridge, Middlesex UB8 3PH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7515-9559","authenticated-orcid":false,"given":"Cristinel","family":"Mares","sequence":"additional","affiliation":[{"name":"College of Engineering, Design and Physical Sciences, Brunel University London, Kingston Lane, Uxbridge, Middlesex UB8 3PH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5598-8453","authenticated-orcid":false,"given":"Tat-Hean","family":"Gan","sequence":"additional","affiliation":[{"name":"TWI Ltd., Granta Park, Great Abington, Cambridge, Cambridgeshire CB21 6AL, UK"},{"name":"College of Engineering, Design and Physical Sciences, Brunel University London, Kingston Lane, Uxbridge, Middlesex UB8 3PH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,24]]},"reference":[{"key":"ref_1","first-page":"V001T01A002","article-title":"Chain out of plane bending (OPB) fatigue joint industry project (JIP) FEA results and multiaxiality study results","volume":"Volume 49927","author":"Rampi","year":"2016","journal-title":"International Conference on Offshore Mechanics and Arctic Engineering"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1115\/1.3226431","article-title":"Corrosion fatigue crack growth of steels in various environments","volume":"111","author":"Alawi","year":"1989","journal-title":"J.
