Özet
The dynamic stiffness method, which yields exact results for certain class of plate structures, is used to analyse free vibration frequencies of various plate assemblies. The constituent plates of the systems are considered either to lie in planes at right angles to each other or coupled via stiffeners. The method is found to work extremely well and excellent agreement is obtained when a comparison is made between computed results and earlier published data. In-plane degrees of freedom are also taken into account in the calculations and it is seen that while for the directly coupled plate assemblies the in-plane effects are negligible for low-order modes, for the stiffened plate assembly the effect of in-plane motion is to reduce the free vibration frequencies. © 1997 Elsevier Science Ltd.
