EPRI (Electric Power Research Institute) reports that 7FA gas turbines have a rotor life of about 144,000 hours, or 5,000 starts. The primary life-limiting factor is high cycle fatigue cracks ...
Achieving high fatigue strength in the 3D-printed NTD-Al alloy (AM NTD-Al). (A) Number of cycles to failure plotted against the maximum stress of AM NTD-Al, compared with other reported 3D-printed ...
Compared to traditional structural materials, polymer matrix composites (PMC) offer greatly enhanced performance and flexibility. However, these benefits come at the cost of increased material ...
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 ...

Estimating fatigue strength in components and assemblies is a frequent engineering task. Doing so is critical to judging a component's durability for both its operational life and that of the ...
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 ...
RAILWAY AGE, APRIL 2022 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic that professionals in the railway industry have asked to learn more ...
