Fatigue Propagation Behavior of Mode II Crack of 30Cr2Ni4MoV Rotor Steel

doi:10.3901/JME.2020.20.088

Abstract

Abstract: The fatigue crack propagation(FCP) rate is important index of mechanical properties for characterizing the fatigue failure of materials, they are the important basis for structural integrity assessment of key projects such as nuclear reactor engineering, chemical engineering, aeronautics and astronautics, and high-speed railway, etc. The Arcan specimens are used to study the FCP behavior of mode II crack of 30Cr2Ni4MoV rotor steel. The fatigue propagation direction of mode II crack is predicted by the existing crack propagation criterion. The results show that the maximum circumferential stress criterion can predict the fatigue propagation direction of mode II crack. The compact tension(CT) specimens are used to study the FCP behavior of mode I crack of 30Cr2Ni4MoV rotor steel. The relationship between the FCP rates and the range of J integral obtained from the fatigue growth tests of mode I crack and mode II crack are compared, and they are very close. Therefore, for the 30Cr2Ni4MoV rotor steel, the results of the mode II crack fatigue growth rates obtained according to the Arcan specimens tests can be used to predict the remaining life of the cracked structures.

Key words: fatigue crack propagation, mode-ii crack, finite element analysis, maximum circumferential stress criterion, J-integral
