Contact Model Framework

The following sections outline the framework that is common to the contact model descriptions. For each contact model, the formulation presentation begins with an introduction, in which the model is described in a few sentences. This is followed by a behavior summary section consisting of a more precise description, including a sketch of the rheological components and associated internal parameters. The activity-deletion criteria are then discussed, followed by the force-displacement law [1]. Finally, the energies, properties, methods, and callback events are listed. These concepts are introduced in the following sections.
