Multiphysics model reduction of thermomechanical vibration in a state-space formulation

The aim of this work is to propose a new multiphysics mode synthesis (MMS) for the thermomechanical vibration problem. present model based on state-space formulation, which consists displacement, velocity, and temperature shift. formulation symmetric unlike conventional non-symmetric displacement In proposed MMS, structural variables, are first reduced, then applied coupling term in thermal parts. A domain reduced while preserving effects, resulting improved accuracy. two-step MMS with physics update can be implemented derived using residual flexibility. strategy also accelerate computational speed independent parallel solvers. performance method evaluated through numerical examples.
