Abstract :

The purpose of this paper is the damping analysis of composite sandwich panels using the Ritz method. Damping is a useful parameter for controlling vibration in moving structures. Due to their high ratio of stiffness and strength to weight, composite sandwich structures have proven their usefulness in a large number of applications in various technical fields, especially in automotive industry and mechanical engineering. In this study, all theoretical calculations were performed using MATLAB software, and damping was evaluated by using the commercial software ABAQUS. The results indicated a good match between the finite element modeling and the theoretical approach.
