# Fatigue Life Prediction Skill

## Purpose

The Fatigue Life Prediction skill provides specialized capabilities for assessing fatigue life and durability under cyclic loading conditions, enabling systematic evaluation of component life using stress-life, strain-life, and fracture mechanics approaches.

## Capabilities

- Stress-life (S-N) curve application and analysis
- Strain-life (epsilon-N) methodology implementation
- Fracture mechanics crack growth prediction (NASGRO, AFGROW)
- Load spectrum development and cycle counting (rainflow)
- Damage accumulation using Miner's rule
- Mean stress correction methods (Goodman, Gerber, Soderberg)
