Frequency Based Substructuring Method for the Investigation of the Dynamic Behaviour of a Beam Structure / Wan Imaan Izhan Wan Iskandar Mirza ...[et al.]
Theoretically, the frequency based substructuring (FBS) method can be used to predict the dynamic behaviour of an assembled structure by combining some parts of the numerical and experimental frequency response functions (FRFs) of the substructures. However, the dynamic behaviour prediction via this...
