Abstract EN
I investigate the vibration and buckling analysis of functionally graded material (FGM) structures, using a modified 8-node shell element.
The properties of FGM vary continuously through the thickness direction according to the volume fraction of constituents defined by sigmoid function.
The modified 8-ANS shell element has been employed to study the effect of power law index on dynamic analysis of FGM plates with various boundary conditions and buckling analysis under combined loads, and interaction curves of FGM plates are carried out.
To overcome shear and membrane locking problems, the assumed natural strain method is employed.
In order to validate and compare the finite element numerical solutions, the reference results of plates based on Navier’s method, the series solutions of sigmoid FGM (S-FGM) plates are compared.
Results of the present study show good agreement with the reference results.
The solutions of vibration and buckling analysis are numerically illustrated in a number of tables and figures to show the influence of power law index, side-to-thickness ratio, aspect ratio, types of loads, and boundary conditions in FGM structures.
This work is relevant to the simulation of wing surfaces, aircrafts, and box structures under various boundary conditions and loadings.
