A survey of various analytical solutions currently used in part-through crack life prediction is presented. Solutions are included which account for shape change effects as well as constant shape solutions. Comparisons of these solutions with constant amplitude experimental data are examined. Results are presented for three different materials: 2219-T851 aluminum, 6A1-4V (β annealed) titanium and 9Ni-4Co-0.20C steel.
