Abstract: Steel cleanliness as measured by nonmetallic inclusion content in steel plays a major role in affecting bearing durability. A highfidelity virtual bearing life test model was developed to predict the impact of inclusions ...

Abstract: The presence of debris particles in rolling element bearings can pose a major risk for premature fatigue damage on modern bearing components made from clean steels. A clear understanding of surface indentation characteristics ...

Abstract: Epicyclic geartrains are known to provide high power density and have become the geartrain of choice for the main power flow in virtually all rotorcraft designs. This paper presents a unique compound planetary design ...

Abstract: The plastic zone developed during elastoplastic contact may be effectively modeled as an inclusion in an isotropic half space. This paper proposes a simple but efficient computational method to analyze the stresses caused ...
