Abstract :
The paper analyzes radar covers formed as shallow shells reinforced by a system of support bars and combined shells of revolution. To analyze stress-strain characteristics, the theory of sandwich orthotropic plates is used, with shear effects taken into consideration. The strength of sandwich walls with honeycomb separation is analyzed as a stress level evaluation, when a local stability collapse of the bearing layers of the construction´s sandwich wall takes place. The reliability and validity of the methods applied are confirmed by experimental investigations.
