Abstract
The factors determining the mechanical properties of plastic polymeric foams are systematized. A unification procedure for their deformation behavior in the range of strains not higher than the forced elasticity limit of the material is proposed. The universal character of the deformation process is described by a unified strain curve and ratios of the main mechanical characteristics of the material, which are independent of the chemical nature of the polymer, the structural parameters of the foam, and the temperature–rate deformation conditions. The deformation behavior of monolithic and foam plastics and inorganic plastic bodies is shown to be similar.
