By using Laplace\u2013Fourier transformations with the eigenvalues technique, the variables are analytically obtained. The derived technique is assessed with numerical results that are obtained from the porous mediums using simplified symmetric geometry. The results, including the displacements, temperature, stresses and the change in the volume fraction field, are offered graphically. Comparisons are made among the outcomes obtained under weak, normal and strong conductivity.<\/jats:p>","DOI":"10.3390\/sym12050848","type":"journal-article","created":{"date-parts":[[2020,5,22]],"date-time":"2020-05-22T10:18:18Z","timestamp":1590142698000},"page":"848","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":128,"title":["An Eigenvalues Approach for a Two-Dimensional Porous Medium Based Upon Weak, Normal and Strong Thermal Conductivities"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5496-0491","authenticated-orcid":false,"given":"Faris","family":"Alzahrani","sequence":"first","affiliation":[{"name":"Nonlinear Analysis and Applied Mathematics Research Group (NAAM), Mathematics Department, King Abdulaziz University, Jeddah 21521, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9407-9650","authenticated-orcid":false,"given":"Aatef","family":"Hobiny","sequence":"additional","affiliation":[{"name":"Nonlinear Analysis and Applied Mathematics Research Group (NAAM), Mathematics Department, King Abdulaziz University, Jeddah 21521, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9595-439X","authenticated-orcid":false,"given":"Ibrahim","family":"Abbas","sequence":"additional","affiliation":[{"name":"Nonlinear Analysis and Applied Mathematics Research Group (NAAM), Mathematics Department, King Abdulaziz University, Jeddah 21521, Saudi Arabia"},{"name":"Mathematics Department, Faculty of Science, Sohag University, Sohag 82524, Egypt"}]},{"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, 500093 Brasov, Romania"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,21]]},"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.
