Microscopic structure, dynamics, and wear at metal-metal interfaces in sliding contact.
The "generic embedded atom model" (GEAM) has been investigated recently [Phys. Rev. E 69, 021509 (2004)]] to analyze the qualitative equilibrium and nonequilibrium properties of bulk metals in both undeformed and shear deformed states. In the present work, a natural extension of the GEAM is proposed and applied to characterize the microscopic structure, dynamics, and wear at clean commensurate ...
متن کاملContact Fatigue
CONTACT FATIGUE is a surface-pitting-type failure commonly found in ball or roller bearings. This type of failure can also be found in gears, cams, valves, rails, and gear couplings. Contact fatigue has been identified in metal alloys (both ferrous and nonferrous) and in ceramics and cermets. Contact fatigue differs from classic structural fatigue (bending or torsional) in that it results from ...
متن کاملSliding contact between freeform surfaces
This paper deals with the sliding-contact constraint equations describing the relative motion of two freeform surfaces, assuming that the surfaces can have arbitrary curvature in 3D space. The sliding-contact equations are developed either for the non-penetration condition and for the surface-tangency condition. Both are differentiated twice in time in order to allow a straightforward applicati...
متن کاملInvestigations of White Etching Crack (WEC) Formation under Rolling Contact Fatigue
A premature failure mode in steel rolling element bearings called white structure flaking (WSF) occurs in wind turbine gearbox bearings. WSF can occur in as little as 6-24 months of operation. WSF is associated with microstructural alterations called white etching area (WEA) and white etching cracks (WECs) that form in the ~1 mm zone beneath the contact surface. The tribological drivers for WSF...
