Abstract

The present investigation deals with the free vibration analysis of a clamped thick five-layered symmetric cross-ply skew laminated Fiber Reinforced Plastic (FRP) composite plate with a circular cutout. Three-dimensional finite element model which uses the elasticity theory for the determination of stiffness matrices is modeled in ANSYS software to evaluate first five natural frequencies of the laminate. The effect of variation of the size of the cutout and the effect of variation of skew angle on the natural frequencies of the plate is discussed.
