论文摘要
我们提出了一种连续理论来模拟穆林斯效应，在聚合物复合材料中观察到了穆林斯的效应。在理论上，通过考虑从纳米/微型填充物中聚合物链的分层来解释材料在拉伸过程中的软化，并且在去脱毛过程中的恢复效果是由于聚合物链的重新分配到纳米/微型/微型/微型填充剂的。通过合并链条纠缠，网络中网格大小的对数正态分布等，我们可以在数值计算结果与现有实验数据之间获得良好的一致性。该物理理论可以很容易地适应以满足更实际的需求，并用于分析聚合物复合材料的机械性能。
We propose a continuum theory to model the Mullins effect, which is ubiquitously observed in polymer composites. In the theory, the softening of the materials during the stretching process is accounted for by considering the delamination of polymer chains from nano-/micro-sized fillers, and the recovery effect during the de-stretching process is due to the reattachment of the polymer chains to nano-/micro-sized fillers. By incorporating the chain entanglements, Log-Normal distribution of the mesh size in the network, etc., we can obtain a good agreement between our numerical calculation results and existing experimental data. This physical theory can be easily adapted to meet more practical needs and utilised in analysing mechanic properties of polymer composites.
