Authors : Ouzeriat Ali . Oud Ouali Mohand . Zrouk Merzak .
Abstract
TheContact between two surfaces with normal and tangential force involve friction dissipationphenomenon.The friction phenomenon can be formulated as a constitutive relation in a similar form to that of the elasto-plastic constitutive equation of materials, the present paper studies of sliding and slip rules of elastic frictional contact by using the formalism of plasticity, for regularized passage from stick to sliding in contact of solids. It purpose is to present new approach for regularized constitutive model for interface contact elastic with friction, this model isimplementedinfinite element code ABAQUS by user subroutine Vfric.
Keywords
