Abstract
An equivalent method based on sandwich plate theory is deduced and the equivalent elasticity modulus of the honeycomb plate are obtained. With these equivalent parameters the multi-interlayer honeycomb plate FEM (finite element method) model is established and FEM mode analysis under different boundary conditions is performed. The difficulty is eliminated that dynamic and static behavior of honeycomb sandwich plates can not be solved directly by using universal finite element programs such as well-known NAS-TRAN. Compared with analytic solution, the results proved the method reliable and applicable for multi-interlayer honeycomb structures.
