In general, the larger the value of Fracture Toughness, the larger the fatigue crack that can be tolerated before triggering a fracture. It is worth noting here that a crack tolerated on a warm summer ...

Fracture mechanics and fatigue analysis remain central to understanding and predicting material failure in metallic systems. These disciplines focus on characterising the initiation and propagation of ...

A key US safety regulator said Friday initial investigations confirm metal fatigue was a factor in last month's scare when a Boeing 777 engine caught fire and rained debris on houses below. But the ...

An investigation into an accident that caused $3.2 million in damage to a NASA-Langley Research Center wind tunnel suggests that engineers reconsider whether the metal band and clamps that caused the ...

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 ...

DAYTONA BEACH — An initial investigation into a plane crash that killed an Embry-Riddle Aeronautical University student and his flight instructor has found that the left wing, which separated from the ...

(Nanowerk News) Metal fatigue can lead to abrupt and sometimes catastrophic failures in parts that undergo repeated loading, or stress. It’s a major cause of failure in structural components of ...

U.S. NTSB investigators determined metal fatigue is suspected as the reason a fan blade fractured just before an in-fight engine failure suffered by United Airlines Flight 328 on Feb. 20, board ...

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

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