The second part of the thesis investigates an existing model of viscoelastic bodies in dynamic contact with a fixed, rigid foundation with Coulomb friction using a Signorini-style, position-based complementarity condition. Existence of solutions to this problem has been previously established. However, no existing results address the issue of energy conservation or balance. We show that solutions to this type of problem not only dissipate energy, but also that the energy lost can be attributed to viscous damping and Coulomb friction losses.The problem of dynamic unilateral contact with friction has been examined in many settings. In , M. Cocou uses a regularization of contact stress and constant friction coefficient to show existence of weak solutions to the dynamic Signorinianbsp;...
