The effect of local rotational deformation of the ribs on compressive buckling behaviors of lattice cylinders is investigated. This type of local deformation may not be embraced in the context of either the global buckling based on smeared/homogenized conventional shell analysis or the local Euler buckling analysis, which are used in the current design methodology of lattice cylinders. Experimental evaluation of the compressive behavior of representative lattice cell structure demonstrated that the rib rotation actually may take place. Beam elements are used in the finite element modeling in order to include the effect oflocal rib rotational deformations. The consequence of considering the effect is the possibility of non-negligible decrease in the buckling load estimation compared to that based on combined methodology of conventional shell buckling, rib local Euler buckling and rib failure strength. The addition of thin skin to the lattice structure is also proposed in order to prevent or reduce the infection of the local deformation nature of the ribs. The merit of supplementing the skin may also arise when the lattice structure is applied to the aircraft fuselage with cabin containment or pressurization requirements. |
