โœฆ Synopsis

Energy equations analogous to the thermal conductivity equation are derived to examine the propagation of longitudinal waves and in-plane shear waves in "nite thin plates. The derived energy equations are expressed with the time-and locally space-averaged energy density, and can be used as the prime equations for the prediction of in-plane structural vibration energy and intensity at middle}high-frequency ranges. To the cases of "nite coupled structures connected at a certain angle, the derived in-plane wave energy equation and developed #exural wave energy equation have been applied by changing the frequency and the damping loss factor to evaluate the proposed methods for the predictions of middle}high-frequency vibration energy and intensity distributions.

Many practical built-up structures, e.g., the modern car body, are essentially assemblies of numerous thin plates joined at many edges. The plates are often so thin that they cannot support appreciable loads out of plane. In the case of a car, the body can only support the static loads of either the

## Abstract The theory for coupling of mapped wave infinite elements and special wave finite elements for the solution of the Helmholtz equation in unbounded domains is presented. Mapped wave infinite elements can be applied to boundaries of arbitrary shape for exterior wave problems without trunca
