At a fatigue crack tip, the occurrence of opening-closure behavior is already known. The opening-closure behavior of a fatigue crack tip is caused by cyclic elasto-plastic deformation of the crack tip. Fatigue strength (S - N curve) and fatigue crack

To clarify the instantaneous strain field during the fatigue crack propagation test, an attempt is made to estimate the displacement vector of the small area of the crack tip from the high speed movie. The key theory of the estimation is Particle Ima

It is clarified that fatigue crack propagation rate of the optimum ferrite-bainite (F/B) steel shows superior resistance in comparison with conventional ferrite-pearlite (F/P) steel. In this study, fatigue crack propagation properties of both F/P ste

Fatigue crack propagation tests have been carried out under various load conditions. Hysteresis loops denoting the relationship between load and strain at the crack tip are obtained by using local compliance measurement. Crack growth acceleration, de

Fatigue cracks of more than several hundred millimeters in length are found and repaired upon maintenance, which is now executed by visual check. These fatigue cracks are detected in and through a secondary phenomenon, as local corrosion, water leaka

In the TMCP steels rolled at the finishing temperature in austenite-ferrite region by the Non-AcC type TMCP method, it becames clear that the fatigue fracture surface had a lot of micro-separations, and fatigue crack propagation was prevented by micr

It was already reported that the fatigue fracture surface for TMCP steels with large SImax. value has a lot of micro-separations which distribute with each length of 0.010.02 mm and with their direction parallel to their plate surface. These micro-se

Most of the previous parameters that utilized as a crack driving force were established in modifying the parameter K op in Elber's effective SIF range ΔK eff ( = K max - K op ). However, the parameters that replaced the traditional parameter K op we
