Free vibration behavior of laminated composite panel with center circular cutout

This research paper describes about free vibration behavior of laminated composite plate withcutout. The kinematic displacement field is based on first-order shear deformation mid-plane kinematics theory (FSDT) with five degrees-of-freedom. The present model is discretized using eight nodesquadrilateral element with forty-eight degree of freedom per element. The Block Lanczos eigenvalue extraction scheme is employed to obtain the natural...
