Mechanical parts are more frequently subjected to cyclic loads than solely static loads. Fatigue issues are commonly observed in turbine blades, aerospace components, locomotive systems, large ...

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 ...

An overview of fatigue failure and how it affects mechanical systems. How FEA software enables engineers to predict fatigue failure points on structural designs, before the manufacturing process. From ...

(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 ...

In some cases, multiple large fatigue crack defects were involved in the wheel failure—so-called multiple site damage (MSD) scenarios. With very rare exception, the broken railroad rails that I have ...

Achieving high fatigue strength in the 3D-printed NTD-Al alloy (AM NTD-Al). (A) Number of cycles to failure plotted against the maximum stress of AM NTD-Al, compared with other reported 3D-printed ...

The causes of gear failure are diverse yet preventable—even tooth degradation and lubrication contamination. Following these ...

Medical devices are true marvels of human ingenuity. They save lives and improve quality of life in countless ways. But what happens when the materials used to make them can't keep up? In vascular ...
