2. Modeling of FG-GPLRC Porous Cylindrical Shell Panel
3. Analysis of Free Vibration Using 2-D NEM
4. Results and Discussion
5. Conclusions
- The numerical method accurately analyzes the free vibration of FG-GPLRC porous cylindrical shell panels, without causing shear locking, with the maximum relative difference of 4.213% even for coarse and 2-D planar NEM grids.
- The normalized natural frequency uniformly increases in proportion to the GPL mass fraction while it uniformly decreases with the increasing value of porosity parameter , and it uniformly increases in proportion to the length–thickness ratio , the length–radius ratio , and the aspect ratio of the shell panel.
- The distribution patterns of both the GPL and porosity significantly affect the variations in with respect to the values of and such that the order of the magnitude of among the four GPL distribution patterns is FG-X > FG-U > FG-Λ> FG-O while that among the three porosity distributions is Porosity_1 > Porosity_3 > Porosity_2.
- The increase in the slope of with respect to the GPL mass fraction is influenced by the GPL distribution pattern, , , and , but it is independent of the magnitude and distribution of the porosity. Meanwhile, the decrease in the slope of with respect to the porosity parameter is influenced by the porosity distribution, but it is independent of the mass fraction and distribution of the GPL and the boundary condition.
