This dataset contains:
The Excel spreadsheet file containing the results that were used to craete the graphs in the paper. 
The .mp4 file showing the crack evolution diagram for sample with OLR 1.56 every 150 baseload cycles.

The figures are as follows:

Fig. 2		Results from three monotonic tensile test results from cylindrical dog bone specimens made from FV566 performed by Frazer-Nash Consultancy

Fig. 6		Number of crack initation sites for the primary crack (The crack that gre the intire width of the notch) for samples with different strain ranges and different surface conditions.

Fig. 9		The number of cracks and number of coalescences that occured between replicas that were part of the main crack versus % lifetime. The total number of crack initiations that make up the main crack on the surface minus the total number of coalescences, resulting in the total number of cracks on the surface versus % lifetime.

Fig. 10A	The short crack replica record and corresponding results for crack growth rate versus deltak for the sample subjected to overloads with OLR of 1.56 every 150 baseload cycles.

Fig. 10A-tab 2 	The short crack replica record and corresponding results for crack growth rate versus deltak for the sample subjected to constant amplitude loading (baseload only).

Fig. 10B	The crack growth rate versus deltaK for long crack experimentation of four samples for constant amplitude loading and with OLR of 1.07, 1.11, and 1.56.

Fig. 11		The results for strain range versus lifetime in number of cycles for all samples tested.

Fig. 13A	The long crack growth rate versus deltaK results for 3 samples made from FV448, FV566 and FV520B for comparitve purposes.

Fig. 13B	The results from short crack and long crack growth rates versus deltaK for the constant amplitude load case.
