摘要：

In this paper, an energy-based approach is developed to investigate damping characteristics of beams partially covered with enhanced self-sensing active constrained layer (ESACL) damping treatments. Analytical formulations for the active, passive, and total hybrid modal loss factors of partially covered beams with ESACL under various boundary conditions are derived. The results show that the edge elements in the ESACL can significantly improve the system damping performance as compared to the active constrained layer treatment. The effects of other key parameters and the boundary conditions have also been investigated.
