Micro Abstract:
Considering a discrete formulation of the frictionless two-body contact problem, we adopt an exact penalty approach in order to enforce the kinematic impenetrability constraints. This approach is based on an augmented discrete force equilibrium and a smooth estimation of the Lagrange multipliers in terms of the nodal displacements. A main feature of the resulting formulation is that an exact enforcement of the impenetrability constraints is achieved for a finite value of the penalty parameter.
