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 ...

Fatigue crack growth and closure mechanisms are fundamental to understanding the durability of engineering structures subjected to cyclic loading. Over decades of research, scientists have ...

The most consequential mechanical failures in transport aviation are often the ones which start as hairline cracks hidden inside a load path that “always worked” until it does not. In the UPS MD-11F ...

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 ...

Fatigue crack growth in aluminium alloys, a phenomenon critical in the design and maintenance of modern aircraft structures, continues to present complex challenges for engineers and researchers alike ...

(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.

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 ...

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 ...

BISMARCK, N.D. (AP) — A fatigue crack in the Keystone Pipeline led to an oil spill in North Dakota earlier this year that released thousands of barrels of oil onto farmland, according to the pipeline ...

A major oil spill from TC Energy Corp.’s Keystone crude pipeline last year was caused by fatigue crack, according to the company. When the pipeline was constructed, a crack formed in a segment of the ...
