DYNAMIC RESPONSE OF FUNCTIONALLY GRADED SKEW SHELL PANEL
Keywords:SKEW SHELL, FUNCTIONALLY GRADED MATERIAL, FINITE ELEMENT FORMULATION, HIGHER ORDER SHEAR DEFORMATION THEORY.
THE DYNAMIC RESPONSE OF FUNCTIONALLY GRADED SKEW SHELL IS INVESTIGATED USING A C0 FINITE ELEMENT FORMULATION. REDDY&RSQUO;S HIGHER ORDER THEORY HAS BEEN EMPLOYED TO PERFORM THE ANALYSIS AND THE VOLUME FRACTIONS OF THE CERAMIC AND METALLIC COMPONENTS ARE ASSUMED TO FOLLOW SIMPLE LINEAR DISTRIBUTION LAW. THE PRESENT STUDY ATTEMPTS TO FOCUS MAINLY ON THE INFLUENCE OF SKEW ANGLE ON FREQUENCY PARAMETER AND DISPLACEMENT OF SHELL PANEL WITH VARIOUS GEOMETRIES. COMPREHENSIVE NUMERICAL RESULTS ARE DEMONSTRATED FOR CYLINDRICAL, SPHERICAL AND HYPAR SHELLS FOR DIFFERENT BOUNDARY CONDITIONS AND SKEW ANGLES. THE FINDINGS OBTAINED FOR FUNCTIONALLY GRADED SKEW SHELL PANELS ARE NEW AND CAN BE USED AS BENCH MARK FOR RESEARCHERS IN THIS FIELD.
