Effects of Variations in Nonlinear Damping Coefficients on the Parametric Vibration of a Cantilever Beam with a Lumped Mass

Figure 8

Typical plots showing the effects of the nonlinear quadratic damping on points 𝐷 and 𝐹. Results obtained with 𝜀𝜎=−0.73,𝜀𝐻₁=0.0 (nontrivial), 𝜀𝐻₁=0.016 (trivial), and 𝜀𝐻₅=62.7218 [19].
