Purpose: The study aims to predict the loss factor properties of composite laminated plates. Design/methodology/approach: Elastic constants of laminates and damping properties have been determined by using an identification procedure based on multi-level theoretical approach. Findings: The present paper is the first attempt at proposing a novel adaptive procedure to derive loss factor parameters for sandwich plate's vibration. Research limitations/implications: In the future the extension of the present approach to sandwich plates with different core materials will be performed in order to test various sandwich design. Practical implications: Structures composed of laminated materials are among the most important structures used in modern engineering and especially in the aerospace industry. Such lightweight and highly reinforced structures are also being increasingly used in civil, mechanical and transportation engineering applications. Originality/value: The main advantage of the present method is that it does not rely on strong assumptions on the model of the plate. The key feature is that the raw models can be applied at different vibration conditions of the plate by a suitable analytical or approximation method.
