Uniformly or non-uniformly distributed internal pores were present in the plates. Based on the modified Halpin-Tsai micromechanics model and the extended rule of mixture, the material properties were evaluated. The governing equations, coupled with the effect of nonlinear foundations, were derived by using the higher-order plate theory and general von Kármán-type equations. A two-step perturbation technique was employed to obtain the nonlinear frequency and transient response. After the present method was verified, the effects of pores, GPLs, and elastic foundations were investigated in detail. A new finding is that the influence of the porosity coefficient on the natural frequency and dynamic response is relevant to foundation parameters. Moreover, the influence of the nonlinear foundation parameter can be negligible. functionally graded porous nanocomposites graphene platelets pores nonlinear elastic foundation nonlinear vibration transient response funkcionalno gradientni porozni nanokompoziti ploščice grafena pore nelinearni elastični temelji nelinearne vibracije prehodni odgovor true false true Angleški jezik Slovenski jezik Članek v reviji 2022-10-13 10:16:34 2022-10-13 10:16:38 2022-10-14 03:58:07 0000-00-00 00:00:00 2022 0 0 Str. 571-582 no. 9 Vol. 68 Sep. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-09-01 534 0039-2480 10.5545/sv-jme.2022.274 125437187 Huang_...-_Nonlinear_vibration_analysis_of_functionally_graded_porous_plates_reinforced_by_graphene_platelets_on_nonlinear_elastic_foundations.pdf Huang_...-_Nonlinear_vibration_analysis_of_functionally_graded_porous_plates_reinforced_by_graphene_platelets_on_nonlinear_elastic_foundations.pdf 1 5B8522DB563B66DE2CAD526868668A6F da4c69b23ea921636f073e23fdbec8322df1928f0cf85d6e02899996c26affee a2376d26-4acf-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163204 https://www.sv-jme.eu/sl/article/nonlinear-vibration-analysis-of-functionally-graded-porous-plates-reinforced-by-graphene-platelets-on-nonlinear-elastic-foundations/ 1 53cf328c-4acf-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163203 Fakulteta za strojništvo Strojniški vestnik 0 0 0
