The large displacement field is express by the first-order shear deformation theory (FSDT) and the von K\u00e1rm\u00e1n nonlinearity, and approximated by 2D natural element method (NEM) in conjunction with the stabilized MITC3+ shell concept and the shell surface\u2013rectangular grid geometry transformation. The nonlinear simultaneous equations are solved by a load incremental Newton\u2013Raphson scheme. The developed nonlinear numerical method is justified from by comparing with the reference solutions, and the load\u2013deflection and bending moment of FG-GPLRC porous cylindrical panels on elastic foundation are scrutinizingly examined. Four different symmetric GPL distribution patters (except for FG-\u039b) and three different symmetric porosity distributions are considered and their combined effects on the nonlinear bending behavior are investigated, as well as the effects of foundation stiffness and GPL amount. Also, the results are compared with those of FG CNT-reinforced porous cylindrical panels.<\/jats:p>","DOI":"10.3390\/sym16020224","type":"journal-article","created":{"date-parts":[[2024,2,13]],"date-time":"2024-02-13T04:09:21Z","timestamp":1707797361000},"page":"224","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Large Deflection Geometrically Nonlinear Bending of Porous Nanocomposite Cylindrical Panels on Elastic Foundation"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5367-4012","authenticated-orcid":false,"given":"Jin-Rae","family":"Cho","sequence":"first","affiliation":[{"name":"Department of Naval Architecture and Ocean Engineering, Hongik University, Jochiwon, Sejong 30016, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1459","DOI":"10.1016\/j.compscitech.2012.05.005","article-title":"The mechanics of graphene nano-composites: A review","volume":"72","author":"Young","year":"2012","journal-title":"Compos.
