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 ...

The fatigue behaviour of welded joints remains a critical area of study due to its profound implications for the longevity and safety of infrastructure and industrial components.

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 ...

A North Carolina Department of Labor investigation found "unidirectional bending fatigue" to blame for the cracked beam that closed the Fury 325 rollercoaster at Carowinds for over a month last ...

Results from a database of over 800 tests were statistically analyzed and used to develop the original AASHTO specifications for fatigue design of welded steel bridge structures.

Canada's TC Energy on Friday said a 14,000-barrel oil spill from its Keystone pipeline in rural Kansas in December was primarily due to a progressive fatigue crack, which originated during the ...

First US use of a steel compression sleeve for pipeline repair confirmed nearly 7 years of Canadian and Mexican experience that the method can permanently repair longitudinal ...

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 ...

When the pipeline was constructed, a crack formed in a segment of the pipe that was welded to a fitting, TC Energy said in an analysis it submitted to federal regulators.
