摘要

裂缝是聚合物领域最重要的课题之一。因此，自20世纪60年代以来，许多关于聚合物压裂的有见地的研究被报道出来。这篇专题综述考虑了实验、理论模型和模拟的聚合物断裂研究。以往的研究主要讨论了裂纹萌生标准、屈服机理以及不同化学物质的断裂差异。基于大规模分子模拟的聚合物断裂也提供了新的见解。

Fracture and Toughening Mechanisms of Glassy Polymer at the Molecular Level

Fracture is one of the most important topics in the polymer field. Accordingly, many insightful works about polymer fracture have been reported since the 1960s. This topical review considers polymer fracture studies of experiments, theoretical models, and simulations. These past studies have discussed craze initiation criteria, yielding mechanisms, and differences in the fracture of different chemical species. New insight into polymer fracture based on large-scale molecular simulations is also provided.

期刊介绍： For the communication among the members, the journal of the Society of Rheology Japan, NIHON REOROJI GAKKAISHI (5 issues per year), was established in 1973 and it is the oldest journal on rheology in Asia. The journal contains original and review articles on rheology and related topics, information for all SRJ events, and reports of domestic/overseas meetings. Articles in Japanese as well as in English are considered for publication, not only from the members but also from the researchers outside. Papers from new emerging areas of the field are particularly welcome. The electronic version of the articles is available via the internet with an open access policy.
