聚合物拉伸过程中颈缩行为的研究进展

Improvement Progress on the Phenomenon of Necking in Polymer Stretching Process

综述了聚合物拉伸过程中的颈缩行为,并从研究颈缩行为的一般内容、颈缩不稳定动力学以及本构理论等方面对颈缩行为的发展历史进行了全面的阐述,最后,探讨了聚合物拉伸过程中颈缩行为的抑制,对未来的研究方向提出了有益的见解。

The necking behaviour in polymer stretching process is reviewed.The common contents studied on necking behaviour,dynamics of necking instabilities and constitutive theory are investigated thoroughly. Moreover,the suppression of necking behaviour in polymer stretching process is introduced and the study topics in the future regarding necking behaviour are proposed.
