The effective stress intensity factor range obtained via the Christopher\u2013James\u2013Patterson model, which provides an effective rationalization of fatigue crack growth rates, is separated into two components representing the elastic and retardation components to assess shielding phenomena on growing fatigue cracks. For this analysis, fatigue crack growth tests were performed on Compact-Tension specimens manufactured in pure grade 2 titanium for different stress ratio levels, and digital image correlation and thermoelastic measurements were made for different crack lengths. A good agreement (~2% average deviation) was found between the results obtained via thermoelastic stress analysis and digital image correlation indicating the validity of the Christopher\u2013James\u2013Patterson model to investigate phenomena in fracture mechanics where plasticity plays an important role. The results show the importance of considering crack-shielding effects using the Christopher\u2013James\u2013Patterson model beyond considering an exclusive crack closure influence.<\/jats:p>","DOI":"10.3390\/ma16165705","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T01:46:56Z","timestamp":1692582416000},"page":"5705","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Study of Effective Stress Intensity Factor through the CJP Model Using Full-Field Experimental Data"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7524-0039","authenticated-orcid":false,"given":"Alonso","family":"Camacho-Reyes","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda Mec\u00e1nica y Minera, Universidad de Ja\u00e9n, 23071 Jaen, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose Manuel","family":"Vasco-Olmo","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Mec\u00e1nica y Minera, Universidad de Ja\u00e9n, 23071 Jaen, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0071-1246","authenticated-orcid":false,"given":"Giancarlo Luis","family":"G\u00f3mez Gonzales","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Mec\u00e1nica y Minera, Universidad de Ja\u00e9n, 23071 Jaen, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco Alberto","family":"Diaz","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Mec\u00e1nica y Minera, Universidad de Ja\u00e9n, 23071 Jaen, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1007\/s10704-008-9209-3","article-title":"Towards a New Model of Crack Tip Stress Fields","volume":"148","author":"Christopher","year":"2007","journal-title":"Int.
