Employing　Reddy＇s　third-order　shear　deformation　theory　(RTSDT)　and　nonlocal　elasticity　theory,　a　nonlinear　bending　model　of　the　nonlocal　three-layer　magneto-electro-elastic　(MEE)　laminated　nanobeam　resting　on　elastic　foundation　is　established　by　considering　von　Karman＇s　geometrically　nonlinear　equations.　Nonlinear　higher　order　partial　differential　governing　equations　of　MEE　laminated　nanobeams　can　be　obtained　employing　Hamilton　variational　principle.　The　three-layered　MEE　laminated　nanobeam　is　considered　to　have　simply　supported　boundary　condition　in　the　present　paper.　Meanwhile,　the　electric　and　magnetic　potential　distributions　in　the　laminated　nanobeam　are　determined　through　Maxwell＇s　magnetic-electro　equations　and　boundary　conditions.　The　governing　equations　of　laminated　nanobeams　are　re-expressed　in　the　dimensionless　form　by　introducing　the　non-dimensional　terms.　Employing　Galerkin　method,　the　nonlinear　higher　order　partial　differential　governing　equations　are　simplified　into　lower　order　equations.　Several　cases　are　explored　to　indicate　the　effects　of　foundation　parameters,　nonlocal　parameter,　stacking　sequence,　external　electric　voltage　and　external　magnetic　potential　on　bending　behaviors　of　MEE　laminated　nanobeams.　©　2022　Elsevier　Ltd
