Papers by Keyword: High Temperature Component

Abstract: In this paper, the key technique involved in life prediction of aeroengine’s high temperature component for creep and fatigue/creep interaction, namely, the life prediction methods for high temperature component are discussed systematically. The essential thinking、features and development direction of the theories are commented in detail. All the results obtained are valuable to engineering applications.

Abstract: This paper describes some recent work on the stress analyses and failure prediction of some typical pressurised high temperature components under creep conditions, including plain pipes, pipe bends, branch connections and welds etc, in the main steam pipework of power plant. The materials used are typically low alloy ferritic CrMoV steels. Experimental creep testing methods, and the procedures used for generating the material properties in creep and damage constitutive equations, are briefly described. Some typical numerical results are presented to illustrate the main characteristics of the behaviour of these components and to demonstrate the effects of geometry, material properties and loading modes on stress distributions and failure life predictions. The emphasis of the paper is on welded components.
