Abstract:

The damping characteristics of nonlinear vibration of a cylindrical panel including large displacements/rotations and parabolic transverse shears has been discussed in this study. The damped results agree with the physical observation in terms of energy dissipation. The two degree-of-freedom damping model will be incorporated for further numerical study in damping characteristics of nonlinear vibration of a composite cylindrical panel with high amplitude.
