Fatigue and Fracture Standards

Fatigue and fracture standards are guidelines that ensure materials and structures can withstand repeated use and stress without failing unexpectedly. Fatigue standards test how materials behave under cyclic loading over time, helping predict potential early failures. Fracture standards focus on the conditions and tests needed to verify a material’s or component's ability to resist crack growth and sudden breaking. Together, these standards ensure safety, reliability, and durability in products like bridges, aircraft, and machinery, providing confidence that they perform safely throughout their intended lifespan under typical operational stresses.
