Modal Analysis of Composite Lattice Plate

A new approach is presented to investigate the dynamic behavior of lattice plate. Shear deformation theory is used. The governing equations and the boundary conditions are derived by Hamilton’s principle. Closed form solution is achieved using the Navier method and solving the eigenvalues. The numerical results of present analysis compared with the FEM results. It indicates that the present theory is more accurate than the other theories for lattice. In this study, the variation of the natural frequency with respect to the various parameters are presented.
