Honeycomb Plate PropertiesDefine the following terms as
t = total face sheet thickness (both sheets together) From classical plate theory, considering only the face sheets to carry inplane stresses: membrane stiffness of plate (Eq. 1) bending stiffness of plate (Eq. 2) (NOTE: Shear flexibility of the plate is not included.) Where I' is the bending moment of inertia of the honeycomb plate per unit width: For d >> t, I' simplifies to:
(Eq. 3) The weight per unit area of the plate is Thus, the stiffness to weight ratios (membrane and bending) are Define nondimensional stiffness/weight ratios membrane bending Instructions for creating a NASTRAN PSHELL card for honeycomb panels.
