Abstract
The structural intensity of a rectangular plate with stiffeners attached is calculated using the finite element method. The power flow behaviors for the plate with stiffeners attached at various positions are investigated. The effects of geometrical properties of stiffeners on the changes of power flow are quantitatively analyzed by numerical integration for the structural intensities. A series of calculation results showed that the total amount of injected or transmitted power flow is dependent on the natural vibration frequency of the whole structure and the relative percentage of power flowing through the cross section of the plate or the stiffener depends on the ratio of their relative flexural rigidity.
