Abstract
A method for correcting the elastic properties of honeycomb sandwich plates by changing the cell shape is described. Compact and convenient analytical expressions (1) are proposed for calculating the reduced elastic parameters of the honeycomb sandwich plates. The acceptable range of changes in the size of the honeycombs is restricted by the cell elongation region β∈[0.5;2] and the region of variation of the angle between cell walls α∈[π/6; 5π/6]. The results of the calculation experiment showed that the traditional cell shape (α=π/3, β=1) is not effective as an optimum structure (Table 1).
