Abstract
AbstractThe present works deals with the incorporation of both flexible beam and shell structures into the realm of flexible multibody dynamics. Geometrically exact beam formulations based on classical Simo‐Reissner kinematics are suitable for modelling beam‐type flexible components in the context of finite‐deformation multibody dynamics. So geometrically exact shell formulations are based on Reissner‐Mindlin kinematics.In [2], a flexible framework for dealing with flexible structural elements in a multibody context is described. A specific isoparametric finite element discretization of a shell formulation leads to semi‐discrete equations of motions assuming the form of differential‐algebraic equations (DAEs). A compatible isoparametric formulation of beams has already been developed in [1].The uniform DAE framework makes possible the incorporation of alternative finite element formulations. In addition to that, various time‐stepping schemes such as energy‐momentum methods or variational integrators can be applied. (© 2010 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
