Abstract: This study proposes a novel passive damping configuration to enhance the static and dynamic stability of sandwich composite (SWC) beams using vibration-damping compound (VDC) coatings. In the proposed design, commercial damping materials, including high-stiffness-based Decidamp SP450 material and low-stiffness-based butyl rubber material, are applied as thin coatings on the outer surfaces of the stiff face layers of the SWC beam. This approach introduces dual-mode energy dissipation through axial deformation (extension/compression) in the coated layers and shear deformation in the viscoelastic core of the VDC-coated SWC beams. A finite element model based on higher-order layer-wise theory is developed to assess the critical buckling load, damping capacity, and parametric instability behavior. The studies include the influence of VDC material properties and coating thickness. Comparative analysis reveals that the Decidamp-coated SWC beam achieves a 3.124% increase in critical buckling load and a 5.02% enhancement in damping compared to the conventional SWC beam, whereas butyl rubber exhibits lower improvements. Additionally, the performance improvements are more pronounced with increased coating thickness. The coating material and its thickness serve as key tuning parameters for tailoring the structural response. The findings highlight the effectiveness and practical potential of VDC-coated SWC beams for passive vibration and instability control in flexible structures, offering a viable design alternative using commercially available damping materials.
