The aim of this work is the development of methods for the numerical simulation of the nonsmooth dynamics of multibody systems involving rigid and/or exible elements which can be subject to frictionless contacts and impacts. These systems are characterized by bilateral constraints which are associated to kinematic joints interconnecting the bodies, and by unilateral constraints stemming from the frictionless contacts and impacts. An additional di culty comes from the presence of exibleelements, with vibration e ects that need to be e ciently captured by the numerical scheme.
