Abstract:
Due to the fact that the analysis of 2D modes can not well reflect the fatigue crack propagation behaviors of container crane, the pipe components of container cranes are studied by 3D crack analysis software Zencrack. The relationship between through crack and partly through crack, and the influence of the initial crack size and load amplitude of the components on life-span of partly through crack are analyzed in detail. It can provide references for counteracting fatigue design and crack propagation management of container cranes' structure.

Note: The Zencrack analyses in this paper were carried out using Zencrack version 7.5 which was released on 12 July 2007.
