摘要
Abstract
A creep lifetime analysis model based on the Lemaitre damage theory was studied,and an improved parameter fitting method combining the modified θ projection technique was proposed.Two different modified θ projection models suitable for different working conditions were introduced,and the specific process of the improved parameter fitting method was described in detail.The creep life of IC10 alloy was analyzed using the Lemaitre creep damage model,and the results were compared with the lifespan analysis results of the traditional Larson-Miller method and Masson-Sokop method.The reserch results show that the improved model has higher analysis accuracy.关键词
