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 analysis and probabilistic modeling constitute a pivotal area in materials science and engineering, addressing the prediction of material degradation and failure under cyclic loading ...

Power boiler startup and shutdown cycling and proper water chemistry are paramount in extending the life and reliability of the unit. Loss of control of either of these processes can cause cracking of ...

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 ...
