Flex Fatigue

ASTM D813, ASTM D430, and ASTM D4482

Summary

Flex fatigue helps characterize a material’s ability to withstand cyclical stresses and strains.

Test Details

ASTM D430 measures the dynamic fatigue on materials through cyclic flexing through surface cracking and break. ASTM D813 provides an estimation of a materials ability to resist crack growth through cyclic flexing of a pierced test specimen. ASTM D4482 helps characterize fatigue life at various extension ratios through looking at full flex-life performance.
