Abstract

Functionally Graded Materials (FGMs) are kinds of composite materials that due to the continuity of mixture of constituent materials as Functionally Graded, have more effective mechanical properties. Also, due to some executive needs, make Opening and Stiffener in shells will be necessary. Therefore, In this paper, the effective parameters on the free vibrations of Functionally Graded plates with Opening and Stiffener have been studied. In order to do this, ABAQUS finite element software has been used, in the first, the effect of important parameters such as Volume Fraction Index, geometric dimensions and plate support conditions have been analyzed. The results show that the thickness and Volume Fraction Index have the highest and lowest effects, Respectively, on the natural frequencies of each of the FGM plate modes and with the increase of simple support conditions in the edges of the plate (the decrease of fixed conditions), the natural frequency of the plate decreases. In the following, the effect of Opening and Stiffener on the natural frequencies of the plate has been observed, that Circular Opening has a greater effect on the natural frequency of the plate than the square Opening, and also the Stiffener thickness has a greater effect on The natural frequency of the FGM plate than its height.
