title = "Flexible multibody dynamics: Which terms of the equations of motion have to be considered for which problem?",

abstract = "Scientists often face the task to carry out a “proof of concept” of a research idea. If this is related to multibody simulation of flexible bodies, it is sometimes necessary to implement a simple and problem-oriented multibody simulation code in programs like Matlab or Scilab. The question then arises, which terms of the equation of motion have to be considered when the flexible body is modelled along the Floating Frame of Reference Formulation. The consideration of all effects leads to very complex expressions and also require costly FE preprocessing. A remarkably simplified version can be obtained, by a strict application of the small deformation assumption to the level of the kinetic energy. But what is the truth in the context of a certain problem? Clear rules are provided, so that a researcher can decide for a particular mechanical system, which terms are required and which ones can be neglected. This work reviews a paper that has been recently published by the authors with respect to this question.",
