Metals will fail suddenly even when the loading has never been exceeded the intended design loads. Metallurgical Failure Analysis has expertise in identifying and solving fatigue failures.

The image at left shows a stainless steel pin that failed in fatigue caused by the stress-concentrations from the poor quality welding.

All sorts of metals and materials will fail because of fatigue when the right factors of:
  • Environment
  • Applied mechanical loading
  • The number of cycles that the loading is applied
