Thispaperpresentsananalyticalapproachtostudythenonlinearbendingbehaviouroffunctionally gradedporous(FGP)platesrestingonthePasternakelasticfoundation.Theporousmaterialswiththreedifferent distribution patterns namely uniform, non-uniform symmetric and non-uniform asymmetric are considered. Governingequations arederived basedontheclassicalplatestheory(CPT)taking intoaccountvon Kárman nonlinearity and neutral surface position. Using the displacement approach in conjunction with the Galerkin
method,theanalyticalsolutionisobtainedforvariousboundaryconditions(moveableandimmoveablesimplysupported).Theeffectofporositycoefficient,porositydistributiontypes,andvariousboundaryconditionson nonlinearbendingbehaviorareinvestigated.
