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 ...

Studying fatigue cracks at the nanoscale: Sandia National Laboratories researcher Ryan Schoell uses a specialized transmission electron microscope technique developed by Khalid Hattar, Dan Bufford and ...

Johns Hopkins University researchers detail a new method for testing metals at a microscopic scale. The research exposes the origins of crack initiation in metals and unravels a method to prevent ...

This comprehensive overview of the whole field of fatigue and fracture of metallic materials covers both the theoretical background and some of the latest experimental techniques. It provides a ...

Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very ...

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 ...

In general, the larger the value of Fracture Toughness, the larger the fatigue crack that can be tolerated before triggering a fracture. It is worth noting here that a crack tolerated on a warm summer ...

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 ...

Metal fatigue may have caused the fuel-line cracks that have grounded NASA’s entire space shuttle fleet, according to independent materials experts. They say the parts of the orbiter’s fuel system ...
