This work deals with the integration of nonsmooth flexible multibody systems\nwith impacts and dry friction. We develop a framework which improves a\nnon-impulsive trajectory of state variables by impulsive correction after each\ntime-step if necessary. This correction is automatic and is evaluated on the\nsame kinematic level as the piecewise non-impulsive trajectory. The resulting\noverall mixed timestepping scheme is consistent with respect to impacts and\nfriction as well as benefits from advantages of the base integration schemes\nused to calculate the approximation inside the time-step. Therefore, we compare\nthe generalized-\α method, the Bathe method and the ED-\α method.\n
