Fatigue Testing
Fatigue testing is a key method for evaluating structural integrity (SI), assessing the potential structural component fractures during in vivo operations. It is essential to conduct fatigue testing under suitable loading conditions with sample sizes determined by the desired reliability and confidence levels. A clear definition of failure must be established before testing, aligning with the failure modes identified in the risk analysis. Additionally, a stress/strain analysis of the structural components during fatigue testing should be carried out to ensure that the test accurately reflects the in vivo stress/strain distribution. After completing the fatigue tests, specimens should undergo detailed inspection for any evidence of notable events such as microcracks in critical fatigue areas, corrosion, or fractures.

Ylabs employs the FT-7026 fatigue testers for structural components fatigue testing or material fatigue strength testing on representative coupon specimens, actual components, or component sections.
Key features of the FT-7206 fatigue testers include:
-
Simultaneous testing of up to 6 specimens
-
Frequency up to 120 Hz
-
Amplitude of up to ±5 mm
-
Displacement control motion
-
Independent force measurement for each specimen
Moreover, Ylabs offers stress/strain analysis consulting services to ensure that the fatigue testing accurately represents the in vivo stress/strain distribution.
