This paper presents the free vibration analysis of functionally graded porous materials (FGPMs) plates,intheframeworkofclassicalplatetheory(CPT).TheplateisrestedonKeer’selasticfoundationwiththe three-parameter elastic model. Functional graded porous material, in particular, open-cell metal foam with porositiesthatvarysmoothlyalongthicknessdirectionaccordingtothreeporositydistributionpatterns:uniform, nonuniform symmetric and nonuniform asymmetric are considered. Based on Hamilton’s principle, the equationsofmotionarederived.Thenumericalexamplesareperformedandcomparedwiththoseavailablein theliteraturetoshowtheaccuracyofthepresentresults.Theeffectofporositycoefficient,porositydistribution patterns,geometricalandKerrelasticfoundationparametersonnaturalfrequenciesareinvestigated.
