For this purpose, the Finite Element Method is applied to analyze a generalized thermoelasticity theory with a relaxation time. For the development of the model, a thermal conductivity that is dependent on the temperature of the orthotropic medium was considered. The boundary condition for the internal surface of a cylindrical hollow is defined by the thermal shocks and the traction on the free surface. The nonlinear formulations of thermoelastic based on thermal relaxation time in orthotropic mediums are abbreviated using the Finite Element Method. The nonlinear equations without Kirchhoff\u2019s transformations are presented. The results are graphically represented to demonstrate how changing thermal conductivity affects all physical values.<\/jats:p>","DOI":"10.3390\/sym14112387","type":"journal-article","created":{"date-parts":[[2022,11,14]],"date-time":"2022-11-14T02:34:58Z","timestamp":1668393298000},"page":"2387","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Thermal Conductivity Study of an Orthotropic Medium Containing a Cylindrical Cavity"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9595-439X","authenticated-orcid":false,"given":"Ibrahim","family":"Abbas","sequence":"first","affiliation":[{"name":"Mathematics Department, Faculty of Science, Sohag University, Sohag 82524, Egypt"},{"name":"Mathematics Department, Faculty of Science, King Abdulaziz University, Jeddah 21521, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1552-3763","authenticated-orcid":false,"given":"Marin","family":"Marin","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Computer Science, Transilvania University of Brasov, 500036 Brasov, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9407-9650","authenticated-orcid":false,"given":"Aatef","family":"Hobiny","sequence":"additional","affiliation":[{"name":"Mathematics Department, Faculty of Science, King Abdulaziz University, Jeddah 21521, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8679-2579","authenticated-orcid":false,"given":"Sorin","family":"Vlase","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Computer Science, Transilvania University of Brasov, 500036 Brasov, Romania"},{"name":"Romanian Academy of Technical Sciences, B-dul Dacia 26, 030167 Bucharest, Romania"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1063\/1.1722351","article-title":"Thermoelasticity and Irreversible Thermodynamics","volume":"27","author":"Biot","year":"1956","journal-title":"J.
