Abstract
Cutouts are inevitable in structures due to practical consideration. In order to investigate the free vibration of functionally graded plates with multiple circular and non-circular cutouts, finite element method is used. The volume fraction of the material constituents is assumed to follow a simple power law distribution. The parameters considered in this paper are as follows: cutout size, cutout location, number of cutouts and different boundary conditions. It should be mentioned that free vibration for FG plates(such as rectangular/skew/trapezoidal/circular plates) with multiple cutouts has not been studied yet and hence the results out coming from this paper may be used as bench marks for future works.
