对高温低周疲劳寿命预测模型的评价

高温低周劳寿命预测方法对于承受变幅载荷的高温构件的设计具有重要意义。本文系统介绍了迄今这方面所取得的研究成果，特别对目前在国内外影响较大的ＳＲＰ等几个ＨＬＦ寿命预测的经典参数模型和近些年发展起来的预测ＨＬＦ寿命的损伤力学方法作了较为详细的评价，并指出存在问题和研究方向。

A Review for HLF Life Prediction Models

High temperature low cycle fatigue (HLF) life prediction models have great significance for design of high temperature structure under cycLic loading. The paper gives a systematical review for the achievements in this field up to now, with emphasis on the six prominent HLF life prediction models,which are SRP, FS, FMDF, DR, SEP and TME models, and the continuum damage mechanics approach to HLF life prediction developed in recent years. The limitations and possible improvements of the models are also discussed.
