| Abstract: | A power flow analysis method was developed to predict the vibrational responses of reinforced beam-plate coupled structures in frequencies ranging from medium to high. This analysis method was successfully applied to simply supported rectangular plates reinforced with multi-parallel beams by utilizing the power flow coupling relationships at the beam-plate junctions and the zero intensity conditions at the plate edges. Through numerical simulations, the power flow energy density and intensity fields of two different plates, consisting of single beam and eight beams, were compared with those of classical displacement solutions, and they show good agreement in terms of the global decay and the attenuation patterns of the energy density. |
