Multibody dynamics is an exciting area of mechanics, which merges various disciplines such as structural dynamics, multiphysic mechanics, computational mathematics, control theory and computer science in order to deliver methods and tools for the virtual prototyping of complex mechanical systems. Multibody dynamics play a central role in the modelling, analysis, simulation and optimization of mechanical systems in a variety of fields and for a wide range of applications. As new methods and procedures are being proposed at a fast pace in academia, research laboratories and industry, it becomes important to provide researchers in multibody dynamics with appropriate venues for exchanging ideas and results. To answer these needs, the ECCOMAS Thematic Conference on Multibody Dynamics was initiated in 2003. Since then the conference is held every two years in changing locations.
