The National Transportation Safety Board (NTSB) has cited evidence of "metal fatigue" as a contributing factor in the engine failure of a Southwest flight that made an emergency landing and resulted ...

Take a wire paperclip. Now, bend it back and forth in the same spot 15, maybe 20 times. Chances are the paperclip will have broken before you finish. This is due to what’s called metal fatigue, which ...

An overview of fatigue failure and how it affects mechanical systems. How FEA software enables engineers to predict fatigue failure points on structural designs, before the manufacturing process. From ...

Mechanical parts are more frequently subjected to cyclic loads than solely static loads. Fatigue issues are commonly observed in turbine blades, aerospace components, locomotive systems, large ...

Fatigue life is a key concern in welded-steel frames for mobile equipment that experience large and varying dynamic loads. For engineers who design welded-steel structures subject to dynamic loading, ...

Achieving high fatigue strength in the 3D-printed NTD-Al alloy (AM NTD-Al). (A) Number of cycles to failure plotted against the maximum stress of AM NTD-Al, compared with other reported 3D-printed ...
