This　work　aims　to　study　nonlinear　vibration　of　rotating　composite　laminated　cylindrical　shells　under　hygrothermal　environment　and　radial　harmonic　excitation.　Based　on　Love＇s　nonlinear　shell　theory,　and　considering　the　effects　of　rotation-induced　initial　hoop　tension,　centrifugal　and　Coriolis　forces,　the　nonlinear　partial　differential　equations　of　the　shells　are　derived　by　Hamilton＇s　principle,　in　which　the　constitutive　relation　and　material　properties　of　the　shells　are　both　hygrothermal-dependent.　Then,　the　Galerkin　approach　is　applied　to　discrete　the　nonlinear　partial　differential　equations,　and　the　multiple　scales　method　is　adopted　to　obtain　an　analytical　solution　on　the　dynamic　response　of　the　nonlinear　shells　under　primary　resonances　of　forward　and　backward　traveling　wave,　respectively.　The　stability　of　the　solution　is　determined　by　using　the　Routh-Hurwitz　criterion.　Some　interesting　results　on　amplitude-frequency　relations　and　nonlinear　dynamic　responses　of　the　shells　are　proposed.　Special　attention　is　given　to　the　combined　effects　of　temperature　and　moisture　concentration　on　nonlinear　resonance　behavior　of　the　shells.
