Analytical simulations of optimum anisotropic linear viscoelastic damping properties

Numerical simulations of orthotropic linear viscoelastic materials indicate that under constant volumetric strains changes in initial moduli result in the largest alterations of dissipated energies. Dissipation responses to constant volume strain inputs equation are material dominated and follow the time shape of the relaxation modulus curves reaching asymptotic values in the region of the fully relaxed moduli. Dissipation responses to harmonic strain inputs depend on both moduli shapes and the forcing frequencies.
