This　paper　is　the　first　attempt,　to　the　best　of　the　authors’　knowledge,　to　explore　the　nonlinear　temperature-dependent　dynamic　responses　of　a　porous　functionally　graded　graphene　nanoplatelet-reinforced　composite　(FG-GPLRC)　cylindrical　panel　subjected　to　a　moving　distributed　load.　The　desired　porous　FG-GPLRC　structure　can　be　achieved　by　reasonably　designing　the　inner　pore　size　and　GPL　dispersion　patterns.　A　temperature-dependent　dynamic　model　is　proposed　by　introducing　the　equivalent　thermo-mechanical　parameters　of　the　porous　FG-GPLRCs　with　the　help　of　the　Halpin–Tsai　micromechanics　model,　extended　rule　of　mixtures,　and　open-cell　metal　foam　model.　The　nonlinear　governing　equations　of　motion　of　nanocomposite　cylindrical　panels　are　derived　based　on　the　first-order　shear　deformation　theory　and　the　standard　Lagrange　equation　with　the　aid　of　von　Kármán　geometric　nonlinearity.　Additionally,　a　closed-form　Navier-type　solution　is　implemented　to　model　the　simply-supported　edges　of　the　structures.　Finally,　the　nonlinear　dynamic　response　is　determined　using　the　Newmark　direct　integration　technique　combined　with　the　Newton–Raphson　iterative　scheme.　A　parametric　analysis　is　conducted,　and　the　results　indicate　that　the　present　model　can　predicate　the　temperature-dependent　buckling　behaviors　and　transient　dynamic　responses　of　the　porous　FG-GPLRC　cylindrical　panel.　It　is　also　found　that　dispersing　more　GPLs　and　fabricating　more　internal　pores　near　the　mid-surface　of　the　panel　can　greatly　reduce　the　response　amplitudes　induced　by　the　moving　loads,　and　the　moving　distributed　load　with　a　shorter　length　can　result　in　a　higher　response.　©　2023　Elsevier　Ltd
