The　enhanced　thermo-mechanical　static　and　dynamic　behaviors　are　investigated　for　the　functionally　graded　graphene　nanoplatelet　reinforced　aluminium-based　(GRA)　composite　plate.　The　partial　differential　governing　equations　of　motion　for　the　static　and　dynamic　analyses　of　the　GRA　composite　plate　are　obtained　based　on　the　first-order　shear　deformation　plate　theory,　von　Karman　nonlinear　geometric　relationship　and　Hamilton＇s　principle.　Numerical　simulations　are　finished　through　using　the　differential　quadrature　(DQ)　method　and　direct　iterative　process.　Three　different　distribution　patterns　of　the　graphene　nanoplatelets　(GPLs)　are　considered,　including　the　uniform　distribution　pattern,　U　pattern,　and　functionally　graded　(FG)　patterns　of　X　and　O　patterns.　For　the　static　analyses,　the　thermal　buckling　and　post-buckling　behaviors　of　the　GRA　composite　plate　subjected　to　the　uniaxial　or　biaxial　in-plane　loads　are　discussed　with　varying　the　boundary　conditions.　For　the　dynamic　behaviors,　the　thermal　linear　and　nonlinear　vibrations　of　the　GRA　composite　plate　are　analyzed　in　details.　The　numerical　results　demonstrate　that　there　are　remarkable　distinctions　among　the　thermo-mechanical　behaviors　of　the　GRA　composite　plates　with　three　different　GPL　distribution　patterns.　The　present　investigations　are　significant　to　the　optimal　design　and　practical　applications　of　the　GRA　composite　plate,　especially　in　the　thermal　environment.　(c)　2020　Elsevier　Masson　SAS.　All　rights　reserved.
