Pages : 36
Book Description
The importance of delay, retardation in the rate of fatigue crack growth, produced by load interactions in variable amplitude loading, on the accurate prediction of fatigue lives of engineering structures is discussed. The effects of a broad range of loading variables on delay in fatigue crack growth at room temperature are examined for a mill annealed Ti-6Al-4V alloy. The results are used to estimate crack growth behavior under programmed loads.

Book Description
Most of the currently available methods for predicting fatigue crack growth in structures do not consider effects due to mixed-mode loading. This is partly due to the limited information available concerning the fatigue crack growth under mixed mode loading. Previous investigations of mixed mode effects on fatigue crack growth have shown that under combined opening and in-plane shear loading, the cracks turn abruptly so that the in-plane shear mode is eliminated [1-3]. Very little data are generated before the crack curvature eliminates the mixed mode loading. The changing orientation of the crack during the test makes analysis of the problem difficult and may cloud the intrinsic fatigue crack growth rate behavior under mixed mode loading. Situations can exist in engineering structures in which cracks may grow in a self-similar manner even under the influence of mixed mode loading. Examples of such situations are radial cracks in bearing races [4] and transverse cracks in rotating shafts under shear and bending loads. The cracks may not change orientation because the in-plane shear component is fully reversed. It is necessary to understand the effects of mixed mode loading on fatigue crack growth in order to properly predict the behavior of these components.

Book Description
The fatigue crack growth of Ti-6Al-4V in the diffusion bond annealed condition was examined in the range of growth rates from 10 to the minus 12th power to 10 to the minus 4th power m/cycle with the use of compact tension and part-through-crack specimens. The effects of cyclic frequency and maximum stress were investigated. Fractured surfaces were examined by scanning electron microscopy over the entire range of crack growth. The fatigue data were fit empirically to a number of crack propagation laws, none of which was able to predict the entire range of crack growth from threshold to unstable fracture. When the fatigue crack growth rates were compared with those of Ti-6Al-4V of other microstructures, it was found that the diffusion bond annealed was among the most fatigue crack resistant of any microstructure examined.
