Abstract
Polymers found regard among engineers and researcher their special proprieties. Now, we find using the polymers at present in the most advanced technically the branches of industry. In construction of machines, more and more often are practical used hyperdeform materials. The group of construction materials, called hyperdeformable, includes among others: elastomers, plastics made based on rubber, thermoplastic structures, such as polycarbonate, gels and sols, composites and foams: open and closed pores. Porous structures are produced on the basis of different materials, synthetic thermoplastic polymers and thermosetting. The problem of porous materials is taken in many research centres in the world. Porous materials (also called cellular plastics, foam plastics or foamed plastics) include gas phase dispersed in a solid phase of polymeric material. Properties of such systems depend on the properties of the polymer warp and cell structure comprising the gas phase.Approach previously used to anticipate and interpret the behaviour of the hyperdeformable structures, using the theory of hyperelastic materials, does not resolve the issue because it only describes the elastic properties. The article presents an original methodology developed structural identification the viscoelastic properties of hyperdeformable materials, and in particular modern construction materials from the group of plastics and composites of elastomers, foams, etc.
