The　magneto-thermo-elastic　interactions　of　a　circular　cylindrical　shell　immersed　in　applied　magnetic　and　thermal　fields　are　modeled　and　the　shell＇　nonlinear　response　and　stability　are　investigated.　The　shell　is　made　of　a　transversely　isotropic,　perfectly　electroconductive　non-ferromagnetic　material.　The　shell＇s　deformation　is　characterized　by　small　strains　and　moderately　small　rotations.　A　geometrically　nonlinear,　first-order　transverse　shear　deformation　shell　model　is　developed　and　Galerkin＇s　method　is　used　for　spatial　semi-discretization.　The　close　connection　between　the　static　nonlinear　response　and　the　temperature-frequency　interaction　is　explored　to　interpret　the　multi-solutions　of　the　nonlinear　response.　Influence　of　prebuckling　deformations　on　the　buckling　results　is　addressed　and　the　significance　of　the　applied　magnetic　fields　on　the　response　and　stability　is　evaluated.　(C)　2010　Elsevier　Ltd.　All　rights　reserved.
