Loading Frequency Dependence of Threshold Behavior of Fatigue Crack Growth in SUS 304 Steel at Elevated Temperature

Autor: Nobuhiro Tagami, Shiro Kubo, Eiichi Tamura

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A. 65:320-328

The loading frequency dependence of fatigue crack growth in the near-threshold region were investigated using constant Kmax test method at 550°C. Crack growth rates at f=30 and 3 Hz in different specimens were compared. To realize intra-specimen com

Near-Threshold Fatigue Crack Growth Behavior of SUS304 Steel at High Temperatures Using Interferometric Strain/Displacement Gage. 2nd Report, Fatigue Crack Growth Behavior

Autor: Shoji Shiotani, Hisanori Enoki, Kiyotsugu Ohji, T.A.P. Kacou, Eiichi Tamura, Yoshikazu Nakai, Shiro Kubo

Publikováno v: JSME International Journal Series A. 42:97-103

Fatigue crack growth tests were conducted at 450, 550, 650 and 700 (°C) using type 304 stainless steel. Crack closure level was measured using the interferometric strain/ displacement gage (I.S.D.G.), described in the previous paper. Crack growth ra

Autor: Kiyotsugu Ohji, Takuya Uemura, TanohAngePrivat Kacou, Shiro Kubo, Hideyuki Tamai, Eiichi Tamura

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A. 64:564-572

Fatigue crack growth tests using center-cracked [M (T)] specimens and single-edge-cracked (SEC) specimens of SUS304 steel were conducted to examine the behavior of fatigue crack growth in the near-threshold regime at 623 K. Crack closure was eliminat

Near-Threshold Fatigue Crack Growth in SUS304 Steel at Elevated Temperatures

Autor: Nobuhiro Tagami, Kiyotsugu Ohji, Shiro Kubo, Eiichi Tamura

Publikováno v: IUTAM Symposium on Creep in Structures ISBN: 9789048156238

Many efforts have been devoted to the study of fatigue crack growth behavior at high temperatures [1–20]. It has been reported that the fatigue crack growth behavior at high temperatures can be classified into cycle-dependent and time-dependent one
