Abstract

For the problem of the retardation of fatigue crack growth caused by single overload, cyclic strain changes in one cycle of the local crack tip region were investigated by using fine-grid-method. From the application of Crack Tip Strain Loop (C.T.S.Loop), the correlation between effective stress intensity factor range (ΔKeffT) defined from the stress range of C.T.S.Loop and crack growth rate ( da dN) was discussed. Moreover, from the strain range of C.T.S.Loop, the correlation between crack-tip strain range (Δε{lunate}T) and da dN was also investigated.
