The
elastic properties of cellular structures of sandwich panel cores depend on
their density. Density depends on a number of geometric parameters of the core
structure. Research is ongoing to find optimal cell sizes with high stiffness
of cores and low relative density. The aim of the investigation was to develop
mathematical models describing the relative density and elastic properties of
periodic cells: hexagonal, auxetic and lattice. Relative density models are
presented as functions of main structural dimensions that affect the shape and
size of individual cells. The analysis of the calculation results revealed that
the relative density of the core cell was determined by: the thickness of the
cell wall, the thickness of the rib, the angle of inclination of the walls and
ribs, the length of the walls and the height of the core. For each of the cell
types, three models were selected, with different geometries but with equal
relative density. Additionally, linear elastic
modulus was calculated, as well as modulus of elasticity and Poisson's
coefficients for selected structures. Based on the above assumptions, reference
cells with the highest mechanical parameters were selected.
