In the image above, different stages of fatigue failure are presented. The “fatigue origin” shows the development of a superficial crack, which then propagates as “beachmarks.” ...

As expected, they saw nanoscale fatigue cracks appearing early on in the experiment. Unexpectedly, however, they also saw the ends of cracks fusing back together roughly 40 minutes later. “Cracks were ...

Biaxial fatigue and the associated crack growth behaviour in metallic materials have become a focal point for both academic and industrial investigations due to their critical implications for ...

They serve as locations at which cracks in the material can form and the process of fatigue causes these cracks to grow during each stress cycle. This is illustrated in the lower diagram. In the ...

Fatigue cracks have been discovered near the point of break on the Southwest Airlines jet that underwent an emergency landing Friday after the roof tore open in mid-air and led to the airline ...

Doubler Hides Crack Afactual report published last week focuses extensively on fatigue cracks on the fuselage of China Airlines Flight 611, a Boeing 747-200 that came apart at the top of climb on ...
