Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts

A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts...
