Fatigue due to repetitive strain is the leading cause of failure in metal components and structures, but new research shows how crystalline structures called nanotwins can slow the accumulation of ...

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 ...

(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 ...

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, ...

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 ...

RAILWAY AGE, JANUARY 2022 ISSUE: Dangerous fatigue cracks develop in sound steel. Here’s how. Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic that ...

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 ...

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 ...

RAILWAY AGE, JUNE 2023 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic about which professionals in the railway industry have asked to ...
