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 ...

Researchers have developed a powerful new method to simulate and predict how cracks form and grow in engineering materials ...

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 ...

(a) Schematic illustration for our precise sectioning technique on the location of fatigue crack initiation; maximum stress and cycles to failure for (b) NAMP state; (c) HIP state; (d) HIP+STA state.

Metallic glasses (MGs) exhibit greater elastic limit and stronger resistance to plastic deformation than their crystalline metal counterparts. Their capacity to withstand plastic straining is further ...

Finally, given a fatigue crack of some size and an applied load of some level, there is a critical material toughness that will trigger a brittle fracture. Figure 2 is a diagram that represents these ...

The fatigue cracking penetrated the fuselage skin and created an approximate 18 x 12in [45 x 30cm] flap in the skin that depressurised the airplane." The investigation revealed that the fatigue crack ...

U.S. NTSB investigators determined metal fatigue is suspected as the reason a fan blade fractured just before an in-fight engine failure suffered by United Airlines Flight 328 on Feb. 20, board ...

Thirty feet.” That was the brief, fatal climb of UPS Flight 2976 before it rolled left and tore into buildings beyond ...

Why modern electronics are so susceptible to thermomechanical fatigue. How multiphysics software tools can aid the design process, resulting in better product longevity. The airbags in your car… the ...

WASHINGTON (AP) — An engine disk that broke apart and forced an American Airlines jet to abort a takeoff in Chicago last week shows signs of fatigue cracking, according to a preliminary report ...
