... and other properties for the beams are listed in Table 1. The rationale for choosing the beam properties shown in Table 1 is to emphasize the different behavior of the wave transmission coefficients under By comparing the results in Figures 10 and 11, one can see that for the L-beam ...

... internal dissipated power is usually calculated as In SEA, a multi-coupled system is divided into a number of subsystems, the coupling loss factors are first individually calculated for each pair of subsystems, and then assembled to form a global matrix for predicting the system responses. The procedure can be illustrated by Figure 12. A system consisting of three coupled components presented in Figure 12(b) can be divided into three pairs of subsystems shown as in Figure 12(a). ...

... procedure can be illustrated by Figure 12. A system consisting of three coupled components presented in Figure 12(b) can be divided into three pairs of subsystems shown as in Figure 12(a). The SEA relationship (global matrix shown in Appendix 2) for the whole system is established by using Equations (38, 39 and 40), and the coupling loss factors in the matrix are derived from each individual pair subsystems. ...
