Application of Finite Element Systems for Calculation of Fatigue Growth of Surface and Internal Cracks

  • I. Lotsberg

Summary

Fatigue growth calculations of through plane cracks, semi-elliptic surface cracks and internal elliptic cracks are described. The analyses are based on the energy release rate method in an efficient combination with the multilevel super-element technique. The fatigue life calculation has been based on Paris1 crack growth formula. Some numerical examples of growth of through crack in a welded cruciform joint, semi-elliptic surface crack in an aluminium plate and internal elliptic cracks in a nickel plate are reported.
