Dynamic substructuring can best be seen as a domain-independent toolset for assembly of component models, rather than a modelling method of its own. Generally, dynamic substructuring can be used for all domains that are well suited to simulate multiple input/multiple output behaviour. Five domains that are well suited for substructuring are: WebDec 27, 2024 · The idea of the Craig Bampton method is to define so-called interface modes, which describe the deformation of the structure due to external loads at the boundaries. For each mode, only one boundary degree of freedom is moved while all others are fixed. The picture below shows the 4 interface modes of the beam example.
