A NUMERICAL-SOLUTION FOR DRY CONTACT BETWEEN 2 VISCOELASTIC ROLLERS

A systematic numerical scheme is developed to solve the steady-state r olling contact problem between two viscoelastic cylinders. The contact problem is formulated as an integral equation in which the contact pr essure and the contact area are to be determined. The analysis is rest ricted to the normal contact problem. A standard linear model is used to characterize the viscoelastic behavior of the bounding solids. The effects of the viscoelastic behavior of the material of the contacting cylinders on the contact pressure distribution, contact area, and sub -surface stress field are studied and discussed.
