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 ...

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 ...

(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.

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 ...

Engine pylons are made boring. When they fail, the chain of loads and dependencies that are usually kept under the carpet is revealed within seconds usually too late to salvage. In the UPS Flight 2976 ...

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 ...
