Material Damping Analysis of a Smart Hybrid Composite Lamina

Abstract

This paper addresses an analytical approach to evaluate the inherent material Specific Damping Capacity (SDC) of a smart hybrid fiber reinforced polymer composite lamina. Analytical equations for the material specific damping capacity have been derived by assuming a linear viscoelastic material property for the constituent fiber-matrix system. The damping properties corresponding to all the six in-plane and out-of-plane applied stresses were considered. Numerical studies are carried out by considering examples for which results are available in the literature. In order to demonstrate the versatility of the present method, the damping analysis of a typical shape memory alloy fiber reinforced hybrid composite lamina has also been made.
