Abstract
This papre studies the analytical models for damping evaluation of composite laminates. For this purpose, the frequency equations for cantilevered laminated beams are derived analytically using the Ritz method, based on Classical Lamination Theory (CLT), First-order Shear Deformation Theory (FSDT), and Higher-order Shear Deformation Theory (HSDT), and then fundamental frequencies and specific damping capacities of the beams with different stacking sequences are calculated numerically. The applicability of each model for damping analysis is discussed from the comparisons of the numerical results and experimental results.
