The Fatigue Crack Growth calculator allows for fatigue crack growth analysis of a cracked part. Cyclic loading is applied in the form of a stress history. The crack growth rate is calculated at each stress cycle, and the crack is grown until failure. See the instructions within the documentation for more details on performing this analysis. See the reference section for details on the methodology and the equations used.
