Damping analysis of composite materials and structures
Source abstract
Abstract
The purpose of the paper is to develop a synthesis of damping analysis of laminate materials, laminates with interleaved viscoelastic layers and sandwich materials. Modelling of the damping of a structure constituted of these different materials is established considering finite element analysis based on laminate theory taking into account the transverse shear effects. Experimental investigation of the damping of the different materials is implemented using beam test specimens and an impulse technique. Modelling applied to the experimental results allows us to obtain the damping parameters of the materials and constituents. Next, modelling is applied to the analysis of the damping of a simple shape structure constituted of the different materials. The results obtained are compared with the experimental results of the frequency response of the structure.
