The National Transportation Safety Board has determined that a fatigue fracture in a critical nose landing gear component led to the emergency landing of Delta flight 1092 in Charlotte, North ...

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 ...

In addition, as reflected by the plot in Figure 4, the Fracture Toughness of rail and wheel steel is rangebound but substantially temperature dependent. That leaves fatigue crack size and temperature ...

Fatigue failure is a common challenge in machine design. For engineers and designers alike, addressing fatigue failure is key to ensuring the integrity of structures and components ...

Rather, it is that higher fracture toughness allows for larger fatigue cracks to exist in the component before failure, making them easier to detect. In summary, there are two basic and broadly ...

Fatigue Fracture: The progressive, localized structural damage that occurs when a material is subjected to cyclic loading, eventually leading to crack initiation and propagation.

Further investigation into the cause of United Airlines Flight 328’s engine failure, which scattered debris over Broomfield last month, confirms “multiple fatigue fracture” on a fan blade ...

But when the team is not sure, it just looks at fracture surfaces (sometimes only a small undamaged fracture surface remains after a multiple-part failure), identifying fatigue or overload failure ...

The jet engine fan blade that broke loose Saturday on a United Airlines plane near Denver, triggering a massive failure leading to the grounding of dozens of Boeing Co. 777s, resulted from metal ...
