Nonlinear finite element modelling investigation of flexural damping behaviour of triple core composite sandwich panels

Damping is a useful parameter for controlling vibration and movement in the design of the structure. The aim of this work is to develop a novel composite with high damping capacity. In this study, flexural damping responses of triple core (aluminium foam and PMI foam and H100 PVC foam) sandwich panels are investigated. A numerical modelling of the flexural damping response was performed using the ABAQUS software. All calculations about the theoretical approach were performed using the MATLAB software. A good match between the finite element modelling and the theoretical approach was obtained.
