Abstract

The elastic buckling of regular hexagonal honeycombs with non-uniform thickness cell edges under biaxial compression is numerically analyzed and presented here. A multi-cell honeycomb structure with appropriate periodic boundary conditions was proposed and employed to calculate the biaxial buckling strengths of regular hexagonal honeycombs with plateau borders using finite element analysis. The effects of solid distribution in cell edges on the biaxial buckling strengths of regular hexagonal honeycombs are evaluated and discussed. Numerical FEA results indicate that the biaxial elastic buckling strengths of regular hexagonal honeycombs depend on their relative density, the solid distribution in cell edges and biaxial stress state. Also, the failure surfaces caused by elastic buckling and plastic yielding for regular hexagonal honeycombs under biaxial compression are developed.
