Vibration and Stability Characteristics of the Laminated Composite Plates (LCPs) for Various Delamination Positions
Most often, the laminated panels undergo delamination due to the manufacturing defects or complicated loading conditions during its working life cycle. In the present work, the effect of position of delamination on the vibration and stability behavior of laminated composite plate (LCP) are examined numerically by developing FE formulation. In relation to this, an eight-noded plate element is taken to mesh the plate by taking in to account of effect of shear deformation. The accuracy of the formulation is assured by co-relating the proposed model with the literature. Various control parameters such as delamination size and position, thickness of the plate, ply orientation and boundary conditions (BCs) are included to study the effect on vibration and stability characteristics. The study shows that the positioning of delamination significantly affects the stability characteristics of delaminated panels.
