Definition

This interface is similar to interface type 7; except for the stiffness which remains constant during the contact. Moreover, after impact a slave node becomes tied to the master surface with or without rebound (flag Itied).

Stiffness

During impact, a mass-less spring with constant stiffness is added in order to push the slave node back. Moreover, as the slave node is tied, a second massless spring is used to maintain the slave node close to its impact point. Depending on whether or not rebound is allowed, these two springs are maintained when the slave node is no longer penetrated (Fig. 5.32).
