Abstract

FREE VIBRATION RESPONSES OF SHEAR DEFORMABLE FUNCTIONALLY GRADED SINGLE/DOUBLY CURVED PANELS UNDER UNIFORM, LINEAR AND NONLINEAR TEMPERATURE FIELDS ARE INVESTIGATED IN THIS ARTICLE. THE MICRO-MECHANICAL MATERIAL MODEL OF FUNCTIONALLY GRADED MATERIAL IS OBTAINED USING VOIGT MODEL IN CONJUNCTION WITH POWER-LAW DISTRIBUTION FOR CONTINUOUS GRADATION. THE MATERIAL PROPERTIES ARE ASSUMED TO BE TEMPERATURE DEPENDENT. THE MID-PLANE KINEMATICS OF PANEL GEOME-TRY IS GOVERNED BY THE HIGHER ORDER SHEAR DEFORMATION THEORY WITH NINE DEGREES-OF-FREEDOM. THE GOVERNING EQUATION OF VIBRATED PANEL IS OBTAINED USING HAMILTONÂS PRINCIPLE. FINITE ELEMENT SOLUTIONS ARE OBTAINED USING A NINE NODE QUADRILATERAL LAGRANGIAN ELEMENT. THE APPLICABILITY OF THE PROPOSED MODEL HAS BEEN EXTENDED THROUGH NUMERICAL EXPERIMENTATION FOR DIFFERENT MATERIAL AND GEOMETRICAL PARAMETERS AND TEMPERATURE FIELDS.
