Cellular solids such as honeycombs and foams are widely used as structural
materials for their low density and high specific stiffness.
Under compression or
shear loading, buckling may occur in cells, and complex deformation modes can
result with sudden variation of the strength characteristics of the cellular
In this paper the behavior of regular hexagonal honeycombs under
general in-plane load is examined by experimental tests and numerical
Moreover, the influence of imperfections on the failure process is
A set of uniform deformation fields is imposed on several
honeycomb models with different imperfections in order to achieve the overall
strength properties, the principal buckling modes and the post-buckling behavior.
All the numerical analyses are performed by me...
