Multiscale simulation and experimental analysis of damping in CFRP structures containing rubber

This paper gives an intuitive numerical multi-scale method to estimate damping in anisotropic viscoelastic hybrid composite structures using finite element analysis. Different CFRP-R (CFRP with Rubber) architectures, both microstructural and macrostructural, are studied compared order maximize but also minimize rigidity loss. Homogenization by virtual DMA frequency domain is performed on representative volume elements (RVE) obtain the effective behaviour of every microstructure. The behaviours used define mechanical laminates which vibratory simulations performed. Interesting advanced discussed regarding materials parameters geometrical aspects experimental results.
