A new parameter for characterization of the crack growth resistance for power plant
materials and structures under elevated temperature is introduced in the form of creep stress …

The effect and mechanism of out-of-plane constraint on creep crack growth rates were
experimentally investigated. The results show that the out-of-plane constraint effect on creep …

A load-independent creep constraint parameter R* was proposed, and its load-
independence was validated using finite element results in previous studies. A fixed …

This paper presents the background and development of a novel 'plastic inclusion'approach
for dealing with the local plasticity which occurs at the tip of a growing fatigue crack …

In order to clarify the effect of constraint induced by specimen size on creep crack growth
behavior of P92 steel welded joint, creep crack tests were carried out on the compact …

Effects of constraint induced by crack depth on creep crack behavior of P92 steel was
investigated by experimental investigation and numerical simulation. Creep crack growth …

The hybrid stress–strain controlled creep-fatigue interaction (HCFI) loadings at various dwell
conditions were conducted on 9% Cr steel at 625° C to investigate the deformation and …

损伤容限设计是为保证含裂纹结构安全而发展的抗疲劳断裂设计方法. 其核心思想是:
承认构件中存在初始裂纹, 基于断裂力学理论对裂纹疲劳扩展寿命和结构剩余强度进行分析和 …

In this paper, the effect of the specimen geometry on the creep crack growth behavior in P92
steel was quantified and six different types of cracked specimens (including C-ring in tension …

The specimen geometry and constraint effects on the creep crack growth behaviour of Type
316H stainless steel at 550° C have been examined over a wide range of load levels using …
