Fatigue Failure Analysis of a Cooling Fan Blade

A paper published in  » Engineering Failure Analysis » on www.sciencedirect.com.

Fatigue failure of holding U-bolt of a cooling fan blade is analyzed. Fractography of the fracture surface reveals the characteristics of a fatigue fracture. Finite element modeling is used for stress analyzing. Analysis of the loading conditions indicates that the bolts are under multiaxial fatigue. ……..
