The formulation of stresses of the honeycomb sandwitch panel in the vicinity of the enbedded stiffner are performed and the solution of the formula is made. Out-of-plane strength of the honeycomb sandwitch panel is derived using the analytical solution. Tests are performed to confirm it. Finite element analysis are also performed. As the result of these analysis and the tests, the stress distribution in the vicinity of the enbedded stiffner are derived and the effects of the face skin thickness and the honeycomb core thickness on the strength of the honeycomb sandwitch panel are also derived.
