This paper addresses the formulation and discrete approximation
of dynamic contact/impact initial-value problems. The continuous problem is
presented in the context of non-linear kinematics. Standard semi-discrete
time integrators are introduced and are shown to be unsuccessful in
modeling the kinematic constraints imposed on the interacting bodies
during persistent contact. A procedure that bypasses the aforementioned
difficulty is proposed by means of a novel variational formulation.
Numerical simulations are conducted and the results are reported and discussed.
