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 ...

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 represents a critical challenge in structural engineering, where repetitive cyclic loading provokes the initiation and propagation of cracks. The field has evolved to include ...

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.

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 ...

Researchers have increased the fatigue threshold of particle-reinforced rubber, developing a new, multiscale approach that allows the material to bear high loads and resist crack growth over repeated ...

In-service lubricant analysis serves both proactive and predictive roles. Proactive measurements—such as particle count, water content, glycol levels, viscosity, and acid number—concentrate on ...
