We present a conservative formulation for the frictional contact forces developed in the framework of an energy-consistent method. Bilateral constrains, that is, joints and rigid links, are imposed using the augmented Lagrange technique, provided that the constraints are exactly satisfied. We propose a formulation based on a penalty method to deal with the contact problem including damping and friction. The numerical scheme guarantees that the energy is consistently preserved or unconditionally dissipated. The treatment of the contact constraint also constitutes a novel aspect of this investigation. It is based on the description of implicit surfaces given an efficient strategy for detecting and evaluating the contact. The numerical tests exhibit a good energy preservation performance. Moreover, we use the proposed formulation to analyze a mechanism including a revolute joint with frictional clearance.
