| Abstract: | In this paper, the geometric nonlinear free vibration problemof the laminated plate with ribs is solved by the energy method and theharmonic balance principle. The discretization is carried by using theapproximate analytical solution with multiplemode to express the displacem-ents. Solutions for different boundary, size and disposition of the laminateson the response of the plate is investigated. The efficiency of the method isverified by the mumerical examples. |
