Elastohydrodynamic lubrication modeling for materials with multiple cracks
Qingbing Dong,Kun Zhou +1 more
TL;DR: In this article, a semi-analytic solution for multiple cracks under elastohydrodynamic lubrication (EHL) contact is presented, which not only takes into account the fluid-structure interactions in the EHL contact but also the interactions among all the cracks.

Thermoelastic contact of layered materials with interfacial imperfection
Xin Zhang,Q. Jane Wang +1 more
TL;DR: In this article, the authors investigated the thermoelastic frictional contact responses of an elastic sphere sliding on an elastic layer-substrate system involving imperfect interfaces and found that a stronger discontinuity of interface displacements causes the contact pressure, temperature, and in-plane compressive stress to decrease, but the inplane tensile stress, out-of-plane (compressive and tensile) stress, and von Mises stress to increase.

On the oil-gas-solid mixed bearing between compression ring and cylinder liner under starved lubrication and high boundary pressures
TL;DR: In this article, the oil-gas-solid mixed bearing characteristics and tribological properties of the top ring under starved lubrication were analyzed and it was found that the high boundary pressure has a significant effect and it can even compare with hydrodynamic lubrication and asperity contact near fire top dead centers (FTDCs).
Journal ArticleDOI
Deterministic solutions and thermal analysis for mixed lubrication in point contacts
TL;DR: In this article, a deterministic numerical model for simulation of mixed lubrication in point contacts is developed, where the nominal contact area between rough surfaces can be divided into two parts: the regions for hydrodynamic lubrication and asperity contacts (boundary lubrication).
Journal ArticleDOI
Three-dimensional contact analysis with couple stress elasticity
TL;DR: In this article, a size-dependent semi-analytical model for the contact of an elastic half-space indented by a rigid sphere within the framework of couple stress elasticity is presented.
