Functionally　graded　material　(FGM)　has　an　important　application　prospect　in　aircraft　engineering,　especially　in　smart　aircraft.　The　dynamic　behavior　of　FGM　has　been　widely　investigated　so　far　but　more　work　is　needed　for　the　porous　FGM　pipes　conveying　fluid.　In　this　paper,　a　sensible　pore　distribution　function　related　with　the　volume　fraction　of　metal　and　ceramic　is　proposed　for　the　dynamic　modeling　of　porous　FGM　pipes　conveying　fluid.　The　maximum　porosity　and　its　corresponding　position　are　taken　into　account　in　the　present　mechanical　model.　The　material　properties　of　the　porous　pipes　are　temperature　dependent　and　can　be　affected　by　pore　distribution.　The　governing　equation　of　the　porous　FGM　pipe　is　derived　and　then　the　exact　solution　of　post　buckling　is　obtained.　The　nonlinear　primary　resonance　is　determined　by　the　multiple　scale　method.　It　is　shown　that　the　effect　of　the　pore　distribution　is　very　significant　on　the　post　buckling　behavior　and　nonlinear　primary　resonance　of　the　porous　FGM　pipes.　The　current　work　is　very　helpful　in　understanding　the　influence　of　pore　distribution　on　static　and　dynamic　behavior　of　pores　FGM　structures　in　engineering　practice.
