基于ASME Ⅲ-5 中800H合金材料数据的高温部件非弹性分析评价方法
Inelastic analysis and evaluation method of high-temperature components based on the material data of alloy 800H in ASME Ⅲ-5
摘要
Abstract
ASME Ⅲ-5 provides the specific and feasible elastic analysis method for the design of high-temperature components,but does not specify the detailed and comprehensive material inelastic constitutive model required to perform inelastic analysis,thus making it impossible for designers to directly perform inelastic analysis evaluation of high-temperature components according to existing codes.The high-temperature component of the steam generator of high-temperature gas-cooled reactor is mainly made of alloy 800H.The inelastic constitutive model was reconstructed according to the isochronous stress-strain curve of alloy 800H provided by ASME Ⅲ-5,and the elastoplastic and creep constitutive models were verified.Then the calculation program was developed using the numerical programming tool of Abaqus subroutine,and the data of the expected minimum stress-to-rupture values and the design fatigue strain range were combined.The strain limit evaluation and creep-fatigue damage evaluation of high-temperature components were realized based on inelastic analysis.Finally,the evaluation results of inelastic analysis method and elastic analysis method were compared by numerical examples,and the application scenarios and advantages of inelastic analysis method were further demonstrated.关键词
