Summary
A novel method named spectral-dynamic stiffness method (S-DSM) is presented in this paper for exact free vibration analysis of plate-like structures made of both isotropic and composite materials. The method has no restriction and is completely general to handle any boundary conditions within any frequency range. The S-DSM integrates the spectral method into the dynamic stiffness method (DSM) by using a number of novel techniques. Exact free vibration analysis is then carried out by applying the Wittrick-Williams algorithm with enhancements. The present S-DSM is superior to other methods such as the finite element or boundary element methods in terms of computational efficiency, accuracy and robustness of results.
