In the January 2022 “Timeout for Tech,” I provided a general overview of metallic fatigue. The key takeaways were these: Fatigue cracks in steel are neither manufacturing defects nor the result of ...

1. A National Institute for Materials Science (NIMS) research team has identified the mechanism by which microscopic fatigue cracks grow in metals, solving a half-century-old mystery. The team ...

Improper maintenance work led to a terrifying Alaska Airlines landing in 2023, with an NTSB report revealing a fatigue crack in the landing gear as the cause.

Fatigue Crack Growth: The progressive extension of microstructural cracks under repeated cyclic loading, eventually leading to material failure. Crack Closure: ...

The fatigue cracks of the NAMP state initiate from the clean PBGBs, which is a common characteristic in the AM microstructure, indicating that we have detected the fatigue resistance of the Net-AM ...

A major oil spill from TC Energy Corp.’s Keystone crude pipeline last year was caused by fatigue crack, according to the company. When the pipeline was constructed, a crack formed in a segment ...

The FAA has issued a critical airworthiness directive for 13 Boeing 757-200 planes to address fatigue cracking risks, specifically around the lavatory service panels.

A fatigue crack analysis performed on the aft trunnion pin fracture surface indicated the crack had been present for at least 797 landing cycles.

Fatigue failure is a failure mechanism which results from the formation and growth of cracks under repeated cyclic stress loading, leading to fracture. It can result in failure at stress levels well ...
