Nonlinear transient analysis of composite laminates undergoing moderate rotations Academic Article uri icon

abstract

  • In the present paper the first order shear deformation moderate rotation shell theory is used for the geometrically nonlinear finite element analysis of large amplitude oscillations of laminated composite plates and shells. The nine-node isoparametric finite element is applied and the nonlinear equations of motion in the Total Lagrangean formulation are solved using the central difference time integration method. The problems considered here concern nonlinear vibrations of plates and cylindrical shells subjected to suddenly applied loading or unloading.
