摘要：

Analytical minimum and central film thickness formulae have been derived for elastic layers firmly bonded to rigid cylindrical substrates under entraining motion when the contact width is significantly larger than the layer thickness. The elastic layer has been assumed to be either a compressible or an incompressible material; the corresponding Poisson's ratios are assumed to be 0.4 and 0.5 respectively. Good agreement has been found between the film thicknesses predicted by these film thickness formulae and some numerical solutions for similar conditions. Good agreement has also been found with the general full numerical solution for incompressible elastic layered surfaces.
