"Metal fatigue" refers to the weakening and damage that occurs in metal materials over time due to repeated stress or loading. It's similar to how our muscles get tired and weaker after exercising too much. The metal becomes more prone to cracking, breaking, or failing, which can be dangerous in structures or machines made with metal.

It's far more lickely to suffer from
metal fatigue in the chassis than any of it's competitors.
«Although much was known
about metal fatigue, not enough was known about it by anyone, anywhere,» lamented Geoffrey de Havilland in his autobiography.
The upshot, the researchers report today in Science, is that the new steel (with its different components shown in red, green, and black dots in the image above) is far more resistant to cracks created
by metal fatigue than conventional steels.

metal fatigue on an engine that exploded Tuesday, sending shrapnel into the plane and killing a passenger seated near a window.
Metal fatigue induced by repeated pressurisation cycles created cracks that started around the plane's window frames.
SMR - 160's ability to load - follow without excessive
internal metal fatigue is, in a manner, another bonus of the gravity driven design.

NEW YORK (Reuters)- Federal investigators on Thursday said the engine fan blade that broke apart during a Southwest Airlines flight last month showed signs consistent
with metal fatigue, as inspectors probe the first passenger fatality on a U.S. airline in nearly a decade.
The identification
of metal fatigue, the degradation of a metal's structural integrity over repeated use, could necessitate more frequent and more comprehensive inspections of these parts.
In several of the worst crashes, either wind shear or
metal fatigue in engines has been identified as responsible for regrettable human tragedies.
Metal fatigue, the degradation of a metal's structural integrity over repeated use, likely caused the fan blade to break apart, according to the NTSB.
A preliminary examination of the blown jet engine showed evidence of «
metal fatigue,» according to the National Transportation Safety Board.
According to Sumwalt, a preliminary examination of where the blade failed found evidence of
metal fatigue.
National Transportation Safety Board investigators found evidence of cracking and
metal fatigue in the area where the blade failed.
The blade was separated at the point where it would come to the hub and there was evidence of
metal fatigue, according to Sumwalt.
Did you ever heard «
metal fatigues» caused plane crashed?
