在役压力容器缺陷评定研究进展

New advances in investigtion of defect assessment of pressure vessels on active service

回顾和总结了在役压力容器缺陷评定和容限分析的发展现状 ,并主要对失效评定图、概率方法、智能方法 (尤其人工神经网络方法 )和疲劳工程评定方法新进展进行了综述 .提出了今后的发展方向和需要着重开展的工作 .

The current development situation relating the defect assessment of pressure vessels on active service is reviewed and summarized and the new advances in the use of failure assessment graph, probability method, intelligence method (especially the artificial neural network method), and fatigue engineering assessment method are emphatically described as a whole. The developing tendency and the task needed to be emphatically developed are also presented.
