Abstract
In this paper were conducted virtual tests to assess the impact of geometry changes on the response of metallic hexagonal
honeycomb structures to applied loadings. The lateral compressive stress state was taken into consideration. The material properties
used to build numerical models were assessed in laboratory tests of aluminium alloy 7075. The modelling at meso-scale level allow
to comprehensive study of honeycomb internal structure. The changes of honeycomb geometry elements such as: fillets radius of
the cell edges in the vicinity of hexagonal vertexes, wall thickness were considered. The computations were conducted by using
finite element method with application of the ABAQUS finite element method environment. Elaborated numerical models allowed
to demonstrate sensitivity of honeycomb structures damage process response to geometry element changes. They are a proper tools
to perform optimization of the honeycomb structures. They will be also helpful in designing process of modern constructions build
up of the considered composite constituents in various branches of industry. Moreover, the obtained results can be used as a guide
for engineers. Conducted virtual tests lead to conclusion that simplification of the models of internal honeycomb structure which
have become commonplace among both engineers and scientist can lead to inaccurate results.
