The definition of the critical levels of microstructural damage that can lead to the propagation of fatigue cracks under high-cycle fatigue loading conditions is a major concern with respect to the structural integrity of turbine-engine components in military aircraft. The extremely high cyclic ...

Ti-6Al-4Vstress ratioAn investigation was undertaken to evaluate the effects of mean stress on the high cycle fatigue (HCF) limit stress under uniaxial loading. Tests were conducted at constant values of stress ratio, R (ratio of minimum to maximum stress), at frequencies from 20 to 70 Hz ...
Influence of foreign-object damage on crack initiation and early crack growth during high-cycle fatigue of Ti–6Al–4V Eng Fract Mech (2000) P. Lukáš Stress intensity factor for small notch-emanating cracks Eng Fract Mech (1987) J.C. Newman et al. An empirical stress-intensity factor equ...
In order to investigate the fatigue behavior of Titanium Alloy in very high cycle region, fatigue test of Ti-6Al-4V was performed at ambient temperature by using ultrasonic fatigue equipment. Fracture surface morphology was observed by using Scanning Electron Microscope. The results demonstrate that ...
The effects of stress ratio on high-cycle fatigue (HCF) and very-high-cycle fatigue (VHCF) behavior of a Ti–6Al–4V alloy were systematically investigated in this paper. Fatigue tests with ultrasonic frequency (20 kHz) were performed on specimens of a bimodal Ti–6Al–4V alloy with stress...
fatigue cracks almost initiate from material inside by the stress ratio R around 0,while on the surface by R around-1 or 1.The formula for estimating fatigue strength of Ti-6Al-4V at different stress ratios was proposed,also.Results reveal that the estimating formula coefficients for thick ...
