Abstract
Analysis of the stored shear stress energy of a vibrating constrained-layer-damping beam to understand the influence of the shear on the damping mechanism. The dynamic mechanical properties of the sandwich structure are measured experimentally using free-vibration theory of beams and are implemented in a FE software. Finally using the mapping of the loss factor across the viscoelastic layer the contribution of the shear is analyzed.| File | Dimensione | Formato | |
