The aim of this work is to propose a new approach to the solution of 3D unilateral contact problems with Coulomb friction in solid mechanics. We consider dynamical systems composed of several bodies with a finite number of degrees of freedom: rigid bodies, or deformable bodies which are spatial approximations of continuous models. Friction between bodies is modelled using a classical formulation of Coulomb's law. After time discretization (or quasi-static approximation), we get at each time step a problem containing complementarity equations posed on a product of second order cones, plus other equations. Several methods have been proposed in the literature for different equivalent formulations of this problem, in particular by Moreau, Alart...
