摘要：AbstractIn many cases, complex dynamical systems consist of separable components. In order to be able to stick to a setup with exchangeable modules, the description of the interface or port that is used for the connection is very important. Classic reduction approaches in substructuring, such as the well-know Craig-Bampton procedure, typically use brute-force methods for the interface description. It is shown that instead of maintaining local ansatz functions for each node at the interface, a semi-global approach can be used. For the derivation of important deformation patterns at the interface, multiple possibilities are considered and compared.
