Modal analysis validates the model, with maximum errors of 8.51% in natural frequency and 5.14% in thickness-direction loss factor, showing high predictive accuracy. Results also indicate that reducing core density enhances damping, causing faster energy dissipation in the thickness direction than in the longitudinal direction.
