摘要
本文分析了圆环链焊缝区存在缺陷的情况下,受静载荷作用后的断裂行为,并进行了细致的运算,从强度和断裂韧性两方面进行了校核,提出了相应的准则,为深入研究提供了一定的科学理论依据。
The fracture characteristic of round-link chains with weld defects under dead load was analysed. Calculations on stress and stress—intensity factors were made, and the related check bases were provided for further research
