Flexible multibody impact simulations based on the isogeometric analysis approach [PDF]
, 2022 Usually detailed impact simulations are based on isoparametric finite element models. For the inclusion in multibody dynamics simulation, e.g. in the framework of the floating frame of reference, a previous model reduction is necessary.
