Abstract: Polythene and polystyrene cushioning materials are viscoelastic materials. Their stress relaxation test curves are studied by a successive residual method. It is shown that the stress relaxation test curves may be expressed by finite number of Maxwell models interconnected in parallel.

Key words: polythene, polystyrene, cushioning material, stress relaxation
