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 ...

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 ...

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 ...

Fatigue life is a key concern in welded-steel frames for mobile equipment that experience large and varying dynamic loads. For engineers who design welded-steel structures subject to dynamic loading, ...

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 ...

A detailed metallurgical examination of a 7/8-in. and a 1-in. sucker rod revealed corrosion fatigue had caused their failure. The 7 to 8-in. rod had failed after a few months of service while the 1-in ...
