Considering　the　condition　of　the　elastic　foundation　and　obeying　Reddy＇s　third-order　shear　deformation　theory,　the　nonlinear　forced　vibration　behavior　of　the　magneto-electro-　elastic　composite　materials　(MEE)　plate　is　studied.　Combined　with　von　Karman＇s　nonlinear　principle　and　Hamilton＇s　principle　for　model　derivation,　the　nonlinear　partial　differential　equations　of　the　MEE　plate　are　obtained,　and　then　the　equations　obtained　are　dimensionless.　Based　on　the　mechanical　model　of　the　nonlinear　forced　vibration　of　the　MEE　plate　and　the　Galerkin　method,　the　nonlinear　high-order　partial　differential　equations　are　reduced　the　two-degree-of-freedom　nonlinear　ordinary　differential　equations　and　the　model　is　analyzed　by　the　multi-scale　method.　In　the　numerical　calculation,　the　influence　of　the　geometrical　parameters,　loads,　damping,　magnetic　and　electric　field　strength　of　the　MEE　plate　on　the　nonlinear　amplitude-frequency　response　curve　(AFRC)　of　the　MEE　plate　is　discussed.　©　2021　Elsevier　Ltd
