| 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. |

| Keywords: | polythene polystyrene cushioning material stress relaxation |
