A new method is proposed to compute by the 3D finite element method ARC3D, the contact stresses of rubber automobile parts. It is based on a surface-to-surface friction contact algorithm.The contact tractions over the quadrilateral surface segments are computed. Coulomb's law of friction is enforced globally over a surface segment. A standard sliding block specimen is computed. Compared with photoelastomeric results, relatively accurate results are obtained.A car door seal is also analyzed. Finally car window seals are stress analyzed. The results correlate well with the experimentally obtained pull-up force.
