“…They compared theoretical and experimental results obtained for carbon fiber and glass fiber reinforced polymer plates (mid-plane symmetric). Kamal et al 10 carried out free vibration analysis to study the vibration characteristics of composite laminates using the modified shear deformation, layered, composite plate theory while employing the Rayleigh-Ritz energy approach. The numerical results for fully clamped boundary conditions and are compared with previously published literature 11,12 .…”

In this work, the natural frequencies and mode shapes of a number of cantilever glass fiber reinforced polymer composites (GFRPCs) and carbon fiber reinforced polymer composites (CFRPCs) are numerically obtained using the commercial finite element analysis software (ANSYS). The laminates under study include 8 ply cantilevered plates having a plate aspect ratio of 2 and fiber volume fractions of 0.3, 0.4, 0.5, and 0.6. The finite element analysis procedure is described. The natural frequencies and mode shapes calculated using ANSYS are first validated with the results obtained from previous literature. The agreement between the two results is found to be excellent. The effect of change in the matrix material, hybridization, and laminate stacking sequence on the natural frequencies and mode shapes are also investigated. It is found that hybridization and orientation of the outermost layer has more significant influence on the natural frequencies of the laminated composite plates compared to fiber volume fraction and change in the matrix material.

“…Few studies on the free vibration of composite skew plates have been made. Kamal and Durvasula (1986) studied the free vibration characteristics of composite laminates using the modified shear deformation layered composite theory by employing the Rayleigh-Ritz energy approach. Malhotra et al (1988) studied the rhombic orthotropic plates using a parallelogram orthotropic plate finite element for various boundary conditions and skew angles.…”

The present paper deals with the experimental studies carried out on free vibration of isotropic and laminated composite skew plates. The natural frequencies were also determined using QUAD8 finite element of MSC/NASTRAN and a comparison was made between the experimental values and the finite element solution. The effects of the skew angle and aspect ratio on the natural frequencies of isotropic skew plates were studied. The effects of the skew angle, aspect ratio, fiber orientation angle and laminate sequence (keeping the number of layers constant) on the natural frequencies of antisymmetric composite laminates were also studied. The experimental values of natural frequencies are in good agreement with the FE solutions. The natural frequencies are found to increase with an increase in the skew angle. The variation of natural frequencies with the aspect ratio is small and negligible both for isotropic and laminated composite skew plates.
