000014925 520__ $$2eng$$aA two–parametric mechanical model is proposed to describe a class of auxetic cellular materials. The microstructure of these materials varies from the regular to re–entrant honeycombs with change of the angle between the nodes of material’s lattice. An interaction among the nodes is described by combination of longitudinal and torsional springs. Effective properties of the solid material corresponding to the given microstructure are determined. It is shown that re–entrant honeycomb structures demonstrate the auxetic properties at any combination of parameters whereas the usual honeycombs can have both positive and negative Poisson’s ratios.
