Optimization of Segmented Constrained Layer Damping Literature Review

Abstract—constrained layer damping has extensively used since many years to damp flexural vibrations by producing shear forces in between constraining and constrained layer. This creates shear deformation is responsible for dissipation of vibration energy. CLD is a sandwiched structure of viscoelastic material between upper constraining layer and base layer. Enhancing the results of damping efficiency of CLD can be achieved by cutting constraining and constraining layer, this is called as segmentation. The main objective of this paper is to provide guidelines for optimization of segmentation of viscoelastic material in between composite structure
