Metals fatigue failures occur when structures are subjected to high stress over an extended period of time. They cause metals to fail at a stresses much lower than they can normally withstand. The ...

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, ...

(Santa Barbara, Calif.) -- 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 ...

Engineers have identified a fundamental deformation mechanism that can be leveraged to greatly enhance the fatigue properties of metals, opening the door to a new strategy for designing ...

Things don’t fall from the sky without a damn good reason. US lawyers Baum Hedlund, who specialize in litigation concerning transport accidents, lists human errors as the main reasons (53 percent) for ...

1. A National Institute for Materials Science (NIMS) research team has identified the mechanism by which microscopic fatigue cracks grow in metals, solving a half-century-old mystery. The team found ...

From titanium and stainless steel to cobalt-chromium, tungsten, and tantalum, a host of metals is used in cardiovascular, orthopedic, and many other medical device fields. However, because metals and ...

During an experiment designed to analyze how metals perform under repeated stress, researchers at Sandia National Laboratories saw something unexpected – a piece of metal that had cracked began to ...
