Calculation of Thermal Stress in Elastohydrodynamic Lubrication of Line Contact
Abstract A numerical method is proposed to calculate the surface thermal stresses of solids in thermal elastohydrodynamic lubrication of line contact. According to the method, the material line thermal expansion coefficients of lubricated contact surface are calculated after obtaining the pressure and temperature that meet the ...

The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...
