Investigation of the asperity point load mechanism for thermal elastohydrodynamic conditions [PDF]
MATEC Web of Conferences, 2019 The rolling contact fatigue damage called pitting or spalling develops more frequently in surfaces with negative than positive slip. Since normal line loads do not cause any tensile surface stresses this investigation considers the effects of small point

A Numerical Study on Thermal Elastohydrodynamic Lubrication of Coated Polymers [PDF]
Tribology Letters, 2020 AbstractThe application of polymers in power-transmitting machine elements, e.g., gears, is limited by moderate thermo-mechanical properties and the detrimental accumulation of contact heat, even with external lubrication. Hence, polymer rolling–sliding elements are often prone to thermo-mechanical overload or abrasive wear.
