Purpose:　This　paper　is　the　first　attempt,　to　the　best　of　the　authors’　knowledge,　to　examine　the　non-linear　blast-induced　dynamic　responses　of　functionally　graded　graphene　platelets-reinforced　composite　(FG-GPLRC)　porous　cylindrical　panels　in　thermal　environments.　Methods:　The　mechanical　properties　of　porous　FG-GPLRC,　including　the　modulus　of　elasticity,　mass　density,　coefficients　of　thermal　expansion,　and　Poisson’s　ratio,　are　determined　by　using　the　Halpin–Tsai　micromechanical　model,　the　extended　rule　of　mixtures,　and　the　open-cell　metal　foam　model.　The　first-order　shear　deformation　theory,　the　von　Kármán　geometric　non-linearity,　and　the　standard　Lagrange　equations　are　applied　to　derive　the　equations　governing　the　motion　the　FG-GPLRC　porous　cylindrical　panels.　Navier’s　solution　is　used　to　model　the　immovable　and　simply　supported　boundary　conditions　of　the　cylindrical　panels.　The　Newmark-β　scheme　for　direct　integration　and　the　Newton–Raphson　iterative　technique　were　used　to　obtain　the　non-linear　dynamic　responses　of　the　FG-GPLRC　porous　cylindrical　panels　when　they　were　subjected　to　various　blast-induced　loads　in　a　thermal　environment.　Results　and　Conclusions:　A　parametric　study　is　performed　and　indicates　that　the　dependence　of　the　properties　of　the　material　on　the　temperature　influenced　both　the　matrix　and　the　GPLs,　and　thus　had　a　significant　influence　on　the　non-linear　dynamic　responses　of　the　structure.　Enhanced　structural　performance　can　be　achieved　by　either　dispersing　more　GPLs,　or　introducing　denser　pores　near　the　upper　and　lower　surfaces　of　the　structure.　©　2024,　Springer　Nature　Singapore　Pte　Ltd.
