Temperature primarily influences thermal elastohydrodynamic lubrication (TEHL) through the temperature dependence of viscosity liquid. The pressure and dependences increase rapidly as glassy state is approached from liquid state, a property known fragility. glass increases with reaches to ordinary temperatures at TEHL pressures. Most analyses have ignored fragility by utilizing correlation inca...

The paper is concerned with prediction of elastic contact and elastohydrodynamic film thickness in worm gears. Using the undeformed geometry of the gap between gear teeth in contact a three-dimensional elastic contact simulation technique has been developed for calculation of the true area of elastic contact under load relative to the wheel and worm surfaces. A parallel investigation of elastoh...

We present an analysis of the planar motion of single semiflexible filaments subject to viscous drag or point forcing. These are the relevant forces in dynamic experiments designed to measure biopolymer bending moduli. By analogy with the "Stokes problems" in hydrodynamics (motion of a viscous fluid induced by that of a wall bounding the fluid), we consider the motion of a polymer, one end of w...
