On finite element models of the buckling and vibration of composite laminates Conference Paper uri icon

abstract

  • The classical, first-order, and higher-order theories of composite laminates are reviewed and their finite element models are described. The effects of boundary conditions, transverse shear aspect ratio and lamination schemes on natural frequencies and critical buckling loads are investigated. The study concludes that shear deformation laminate theories accurately predict the behavior of composite laminates, while the classical laminate theory over-predicts natural frequencies and buckling loads. It is also noted that care must be exercised in using symmetries in analyzing certain composite laminates, or else significant errors will be introduced into the solution.
