含缺陷压力容器的概率失效分析研究进展
Review on failure analysis of pressure vessels containing defects based on probabilistic fracture mechanics
摘要
Abstract
The statistical model and the evaluation method of the failure probability play a key role in the probability fracture mechanics analysis of pressure vessels containing defects.In this paper,a survey is conducted on the recent progress of the failure analysis and safety reliability assessment of pressure vessels containing defects under different conditions in terms of the probabilistic fracture mechanics.With the review of statistical characteristics of material strength,toughness,temperatures,defect scales,detection rate,and other uncertainty factors,the frequently used evaluation methods of failure probability for pressure vessels are surveyed.Furthermore,three evaluation methods,namely,directly analytic integral method,approximate method and numerical simulation method,are analyzed in details.It not only provides some feasible methods for handling practical engineering problems,but also proposes some challenging theoretical problems in this field.关键词
