FINITE ELEMENTS FOR THE LUBRICATED CONTACT BETWEEN SOLIDS IN METAL FORMING REOCESSES

Abstract

Abstract: In this paper, the lubrication problem in nmmerical sindation of forming processes is considered.After enumerationg the difficulties encountered when trying to solve such a problem with the finite element method, a generalization of the formaulation of Liu[4-6] for the thin film hydrodynamic lubrication re- gime is presented. This method is then aplied to a strip rolling simulation,using the Arbitrary La- grangian eulerian (ALE) formalism.

Key words: finite elements, lubrication, ALE, strip rolling simulatin
