Short and Large Crack , Mixed - Mode Fatigue - Crack Growth Thresholds in Ti - 6 Al - 4 V
There are few experimental results to date describing the crack-propagation threshold behavior of short fatigue cracks under multiaxial loading conditions. To address this need, in the present study, the variation in mixed-mode, high-cycle fatigue-crack growth thresholds with crack size and shape are reported for a Ti-6Al-4V turbine blade alloy, heat treated to two widely different microstructu...
متن کاملEffect of Boundary Condition on Pre-Existing Crack Under Fatigue Loading
In this paper, the present investigation has been conducted keeping in mind some of the problems concerning the crack propagation direction and growth under constant loading in an inclined crack geometry. The present studies mainly focused on the development and modifications in the crack growth criterion to account the biaxial, shear loading and number of stress terms. Existing criteria for th...
متن کاملMixed-mode, high-cycle fatigue-crack growth thresholds in Ti– 6Al–4V: Role of small cracks
There have been few studies to date describing fatigue-crack propagation thresholds under mixed-mode loading conditions in the presence of cracks, that are small as compared to the characteristic microstructural dimensions. To address this need, the variation in mixed-mode, high-cycle fatigue-crack growth thresholds with crack size is reported for a Ti-6Al-4V turbine blade alloy with a fine-gra...
متن کاملMixed-mode, high-cycle fatigue-crack growth thresholds in Ti±6Al±4V II. Quanti®cation of crack-tip shielding
The role of crack-tip shielding in in ̄uencing mixed-mode (mode I II) fatigue-crack growth thresholds for large, through-thickness cracks in a Ti±6Al±4V turbine blade alloy is examined under high-cycle fatigue loading conditions, i.e., at a loading frequency of 1000 Hz in ambient temperature air for load ratios (Kmin=Kmax) of R 0:1±0.8. Techniques are developed to quantify crack-tip shielding...
