Why liquid oil turns to glass
Discover why liquid oil turns to glass under extreme pressure in mechanical engineering. We break down the glass transition in lubricants, elastohydrodynamic lubrication (EHL), piezoviscous effects, capillary and boiling limits, how oils vitrify into a solid-like glassy state at GPa pressures in rolling bearings and gears, plus the physics that control film thickness, traction, and failure when calculations assume liquid behavior but reality is glassy.
