Abstract
Mutli-layered structures (such as sandwich panels) are commonly used in engineering applications for the improved sound comfort and noise reduction. Finite Element modelling of these layered structures would often results in increased total number of degrees of freedom which would lead to high computation time. An alternative to the full modelling of multi-layered system is the use of equivalent plate models to simulate the multi-layered system as a single layer. These models would aims at reducing the number of degrees of freedom in finite element models. Applicability of these models would be limited up to certain frequency range due to underlying assumptions of wave propagation in each layer. In this work, these equivalent plate models are compared using wavenumber analysis. Sandwich panels of different types (soft and stiffer cores) are considered for this comparison study and behaviour of each model are analysed.
