An Efficient Numerical Model of Elastohydrodynamic Lubrication for Transversely Isotropic Materials
Zhanjiang Wang,Yinxian Zhang +1 more
TL;DR: In this paper, an elastohydrodynamic lubrication model for a rigid ball in contact with a transversely isotropic half-space is constructed, where the surface vertical displacement or deformation is considered through the film thickness equation and the numerical methods are verified by comparing the displacements and stresses with those from Hertzian analytical solutions.
