Variable Amplitude Fatigue Crack Growth

Fracture initiation occurs at material flaws, irregularities, or as a result of local strain hardening. If undetected or untreated, fatigue cracks can lead to material failure with drastic consequences. Fatigue crack testing is conducted on a wide variety of structural materials including metallic materials, ceramics, plastics, and engineered composites.
