Abstract

Frictional contact laws between two solids undergoing large displacements and large strains are established considering that a thin interphase is being created in the vicinity of the contact area. Using the framework of irreversible thermodynamics, evolution laws are derived which couple the irreversible behaviour of the interphase to the velocity of the convection which defines the domain variation due to the creation of a third body. A material surface model for the interphase is next derived. In that way, contact laws with friction under large strains are obtained in a deductive manner, including unilaterality conditions. 1 Introduct
