Abstract

This paper investigates a method to decide which mechanical modes need to be retained in a modal truncation for a thermomechanical problem. A more efficient reduction basis is formed by looking into more detail in the modal participation of the different mechanical modes. Based on the spatial matching properties of mechanical modes with thermal modes can be decided which modes need to be retained in the reduction basis. Based on the spectral distribution of the thermal load an extra weighting on this decision is introduced.
