摘要: 用逐次残余法分析了聚乙烯和聚苯乙烯缓冲材料的应力松弛试验数据.结果表明可用有限个并联的Maxwel模型来表示这两种材料的应力松弛试验曲线.

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
