Abstract
We use a Lagrangian finite element method to simulate experiments on continued and interrupted extensions of a highly entangled monodisperse polymer melt. It is demonstrated that delayed sample necking or rupture may be explained in terms of the original Doi-Edwards model augmented by the mechanism of chain stretching alone.

我们使用拉格朗日有限元方法来模拟高度缠结的单分散聚合物熔体连续和间断拉伸的实验。结果表明，延迟的样品颈缩或破裂可以仅通过链拉伸机制增强的原始Doi-Edwards模型来解释。
