Numerical Study and Analysis of Functionally Graded Double Curved Panels

The primary objective of this study is to investigate the linear and free vibration analysis of functionally graded doublecurved shells, using higher-order shear deformation theory using Matlab numerical programming. The mechanical properties of the plate are supposed to vary continually in the direction of thickness and the volume fractions of the constituents are obtained using two types of four-parameter power-law distribution. A continuous isoparametric lagrangian model is used to develop fundamental equations for FGM shells. Convergence tests carried out, followed by an extensive literature validation to highlight the accuracy and efficiency of the current FG model. Two types of FGM combinations namely Al / Al2O3 , Al / ZrO2 , with boundary conditions, geometric parameters, and the consequence of the four parameters are considered for the present study. Finally, some numerical problems were addressed with different volume fractions and boundary conditions to investigate the frequency response of double-curved shells.
