... overloads. It is found that the compressIve load cycles have a remarkable effect on crack propagation as well as crack initiation. Particularly, it is noticeable that, under high baseline load ratio wi- thout crack closure, the non-propagation crack arrested by single peak tension overload recommenced...

... method of measuring the damage factor is put forward By processing data obtained from fatigue experiments with surface crack propagation. The determination of steel damage parameters for offshore structure member's is provided. This new mathematical model is verified by the fatigue experiments of rigid...
