Resumen:
The present work deals with the dynamic analysis of flexible, nonlinear multibody systems undergoing intermittent contact. The contact event is assumed of finite duration and the contact forces are computed during the simulation. Two kinds of contacts are considered: rigid contact condition, treated by using the slack variable technique, and flexible contact, treated by using suitable phenomenological laws that relate the contact forces and the inter-penetration between bodies. The work is developed within the framework of an energy preserving time integration scheme, that provides unconditional stability for the kind of systems analyzed in this work.
