“…Three different types of orthotropic materials namely (1) Carbon/Epoxy, (2) Kevlar49/Epoxy and (3) E-Glass/Epoxy are used for the analysis. These three material properties Ramakrishna [3] and Isaac [9] are provided in Table II.…”

“…The different arrangements of hybrid laminates considered are 1/2/1/2, 1/2/2/1, 2/1/2/1, 2/1/1/2, 1/3/1/3, 1/3/3/1, 3/1/3/1, 3/1/1/3. The first material laminate is taken as carbon/epoxy (1), the second material laminate is taken as kevlar49/epoxy (2) and the third material laminate is taken as E-Glass/ Epoxy (3). For this hybrid laminate arrangements, the different lamination schemes are taken 0/0/0/0, 0/90/90/0 and 90/90/90/90.…”

“…Kant et al [2] studied a higher order shear deformation theory with C o Finite Element formulation for vibrational analysis of unsymmetrical laminated plates. An eightnoded hybrid-stress finite element is used by Ramakrishna et al [3] to analyse the dynamic behavior of laminated plates with cutouts. Yook-Kong Yongt et al [4] presented the finite element formulation for an orthotropic composite plate and shell analyses by using a higher order, partial hybrid stress method.…”

The present investigation deals with the influence of hybrid materials of specially orthotropic nature in free vibration analysis of a thick four-layered Fiber Reinforced Plastic skew laminated composite plate with a circular cutout. Three dimensional finite element models which use the elasticity theory for the determination of stiffness matrices are modeled in ANSYS software to evaluate first five natural frequencies of the laminate. The effect of various hybrid arrangements on the first five natural frequencies of the plate is discussed.

“…Bicos and Springer [16,17] applied Reddy's higher order theory [15] and "nite element methods for the free damped and undamped vibration of laminated composite plates and shells with a concentric circular hole. Ramkrishna et al [18] used an eight-noded hybrid-stress isoparametric "nite element for the free vibration analysis of simply supported laminates with a concentric elliptical hole. Young et al [19] presented a Rayleigh}Ritz approach using the three-dimensional elasticity theory for the analysis of the free vibration of isotropic, thick, rectangular plates, with depressions, grooves, or cutouts.…”
