BEHAVIOR OF SHORT FATIGUE CRACKS AT BLUNT NOTCHESIN A MEDIUM CARBON STEEL

Z.X. Wu and X.F. Sun ( Institute of Applied Mechanics , Southwest Jiaotong University , Chengdu 610031 , China State Key Laboratory for Fatigue and Fracture of Materials , Institute of Metal Research , Chinese Academy of Sciences , Shenyang 110015 , China)

金属学报(英文版)

The behavior of part-through and through short cmcks in single edge blunt notched specimens of a medium carbon steel was investigated by a replication method. It is found that the fatigue failure of these notched specitnensis caused mainly by the growth of short surface cracks originating from the s...

THE STRAIN CYCLIC CHARACTERISTICS AND RATCHETING OF U71Mn RAIL STEEL UNDER UNIAXIAL LOADING

G.Z. Kang , Q. Gao , X.J.Yang and Y.F. Sun(Department of Applied Mechanics and Engineering , Southwest Jiaotong University , Chengdu 610031 , China)

金属学报(英文版)

An experimental study was carried out of the cyclic behavior of U71Mn rail steel subjected to uniaxial strain and stress. The effects of cyclic struin amplitude, mean struin,strain loading rate and their histories on the strain cyclic characteristics were studied.Under the asymmetrical stress cyclin...

A PROBABILISTIC ASSESSMENT OF TEMPERATURE EFFECTS ON THE LOW CYCLE FATIGUE BEHAVIOUR OF 1Cr_(18)Ni_9Ti STEEL WELD METAL

Q. Gao , Y.X. Zhao and L.X. Cai (Institute of Applied Mechanics , Southwest Jiaotong University , Chengdu 610031 , China)

金属学报(英文版)

Based on the test results obtained from the single-step test and the incremental-step test at room temperature and 240℃, a probabilistic assessment of temperature effects on the cyclic stress-strum response and the fatigue life of 1Cr18Ni9Ti steel weld metal is performed. In orber to assess the temp...
