Steam turbine blades are critical components in power generation, and their failure can have profound economic and safety implications. Recent studies have underscored the importance of understanding ...

Repeated inspections revealed fatigue concentrations around the C-123’s wing roots and spars, especially on aircraft operating from rough forward strips. These findings resulted in revised maintenance ...

Inside the massive testing hangars across Seattle and Everett, the world's biggest jetliners are turned into mechanical lab rats. Hydraulic actuators yank their wings skyward, compressors simulate ...

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 ...

When designing printed circuit boards (PCBs), keep in mind the major causes of electronic failure: thermal cycling, vibration, and mechanical shock and drop. You can perform a variety of physical ...

Lloyd's Register (LR) gives shipowners and operators a new tool to help assess designs and reduce the risk of fatigue damage in the hull structures of their ice-strengthened vessels. The development ...

The fatigue-life contour plot of an aluminum suspension component was generated by fe-safe from Safe Technology Ltd., and a finite-element computer model. The software correctly predicted failure ...

How controlled reconditioning of railcar truck components prevents failure chains, improves reliability, and reduces unplanned maintenance.

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 ...

Thermocouples function on the principle of the Seebeck effect, which states that two dissimilar metals combined at two junctions produce an electromotive force, or EMF, at the junctions. The metals ...
