Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.
Bending of plates or plate bending refers to the deflection of a plate perpendicular to the plane of the plate under the action of external forces and moments the amount of deflection can be determined by solving the differential equations of an appropriate plate theory the stresses in the plate can be calculated from these deflections.
