Fatigue Failure Predictions Based on FEA Fracture

Cyclic loading leads to formation of a crack with the depth such that a failure point in the S-N curve corresponds to the 25% load drop. Stress intensity factors are calculated, and number of cycles to failure are determined based on Paris law and a two-stage crack growth relationship.
