摘要

摘要: 应变范围区分法(strain range partitioning,SRP)是由Manson等人于20世纪70年代初发展的一种蠕变疲劳寿命预测方法,经过不断发展和完善,成为少数几种获得实际工程应用的方法之一,并被推广应用于热机械疲劳寿命预测。本文中对SRP法的发展和应用状况进行了梳理综述,重点对基于应变范围区分法发展的总应变-应变范围区分法(total strain version of strain range parti-tioning,TS-SRP)的基本思想和建立过程进行了详细介绍,最后总结给出了TS-SRP法的基本方程、材料参数及其相关关系。

Abstract: Strain range partitioning(SRP) is a method developed by Manson and his colleagues during the early 1970s for creep-fatigue life prediction.Through years of research and development,SRP method have become one of the few methods gained engineering application,and is extended to thermomechanical fatigue life prediction.To promote further research and application of SRP and the derivative methods in China,the development and application status of the SRP method was reviewed and summarized in this paper.The basic idea and formulating processes of the total strain version of strain range partitioning(TS-SRP) were introduced and explained in detail.Finally,the basic equations,material parameters and their correlations were summarized.
