摘要
介绍了评价管材料耐慢速裂纹增长性能的3种实验方法:管材切口实验、全切口蠕变实验和宾夕法尼亚州切口实验的研究进展情况,并对3种方法进行深入分析和对比,可为管材料的研究和性能评价提供参考。
This paper reviews three main tests including notch pipe test （NPT）, full-notch creep test （FNCT） and Pennsylvania notch test （PENT） through which the resistance to slow crack growth behavior of polyethylene is evaluated. Analysis and comparison of the three tests are made to provide reference to the research and performance evaluation on pipe materials.
