The　present　study　is　concerned　with　the　nonlinear　vibration　characteristics　of　laminated　composite　plates.　Considering　the　geometric　nonlinearity　of　plates,　the　vonKarman　large　amplitude　theory　is　used,　and　the　finite　element　method　(FEM)　is　proposed　for　the　present　nonlinear　model,　using　Hamilton＇s　principle,　the　equation　of　motion　of　the　composite　laminated　plates　is　established.　Comparisons　of　the　present　results　with　those　published　in　open　literatures　show　the　accuracy　and　correctness　of　the　present　methodology.　Moreover,　the　nonlinear　vibration　of　composite　laminated　plates　under　the　harmonic　excitation　force　is　discussed　in　time　domain.
