...R. Sugiura; A.T. Yokobori, Jr.; T. Nakagawa; T. Adachi; I. Nonaka; M. Tabuchi; Y. Hasegawa; T. Matsuzaki A testing method under creep-fatigue interaction conditions has been proposed as the ASTM standard E2714-09. In accordance with the ASTM standard, round bar smooth specimens have been...

... as a function of cycle number under hold-time creep-fatigue loading. The Stress Relaxation Model predicted the stress relaxation curve during the hold time of cyclic loading, based on the creep properties of the material. The Interactive Damage Rate Equation predicted the hold-time creep-fatigue life using...

...Mike W Spindler; Warwick M Payten The thermal mechanical cycling of high temperature components can result in creep-fatigue cycles in which the creep dwell has a wide variety of positions within the cycle. During in-phase cycling the creep dwell is placed at the maximum strain in the cycle. Out...

... for nuclear construction requires a detailed understanding of the creep-fatigue behavior. Strain-controlled low cycle fatigue (LCF) tests including hold times up to 1800 s at maximum tensile strain were conducted at 950°C and a total strain range of 0.3 % in air and in a simulated VHTR impure helium...

... fatigue behavior and creep data of smooth specimens. A suitable model for the assessment of the reduction of fatigue life in creep-fatigue conditions is proposed. Mauro Filippini1 Journal of ASTM International, Vol. 8, No. 6 Paper ID JAI103735 Available online at www.astm.org Creep-Fatigue at High...

...V. Kalyanasundaram; A. Saxena; S. Narasimhachary; B. Dogan The American Society for Testing and Materials (ASTM), through its Committee E08 on Fatigue and Fracture subcommittee E08.05 on Creep-Fatigue Crack Formation, has recently developed a new standard for creep-fatigue testing (ASTM E2714-09...

..., the inhomogeneous microstructure strongly affects the crack propagation behavior in such a structure. The authors investigate the effect of microstructural inhomogeneity on crack propagation morphology and crack propagation rate ( da / dN ) under a creep-fatigue condition. The macroscopic direction of the main...
