N2 - The elastohydrodynamic lubrication (EHL) characteristics of transversely isotropic materials are investigated. A finite element method (FEM) is utilized to solve the Reynolds equation, elastic equation, and load balance equation simultaneously on a ball-on-plane equivalent model. A simplified problem related to cornea and contact lens during blinking is studied. The pressure and oil film thickness distributions, surface deformation, and friction coefficient are discussed for various material properties (Young's modulus) and operating conditions (sliding velocity and load). Results reveal that the effects of soft transversely isotropic materials on lubricating performances are significant, which are helpful to further investigate the biomechanical interactions between a keratoconic cornea and a lens during blinking.
