Nonlinear Free Vibration Analysis of Laminated Composite Cylindrical Shells with Cutouts.

The nonlinear free vibration of laminated composite cylindrical shell panels in the presence of cutouts is investigated. The finite element model using an eight-noded C0 continuity, isoparametric quadrilateral element is used to study the dynamic behavior. The nonlinear eigenvalue problem is solved by using the direct iteration method. Parametric study is carried out varying the aspect ratios, lamination schemes and material properties of cylindrical shell with simply supported boundary condition in the presence of cutouts.
