In the work presented in this contribution we have investigated the reduction of dynamical thermo-mechanical systems and we propose a new reduction method that can be seen as an extension of the common Craig–Bampton method Craig and Bampton (1968) [2] where multi-physics is now implicitly included in the projection basis. The efficiency of this new approach has been evaluated in multiple configuration of a representative thermo-mechanical model.
