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

Figure 7

Typical response-amplitude curve demonstrating the effects of varying the quadratic nonlinear damping term (𝜀𝐻₂) for 𝜀𝜎=−0.73. Also 𝜀𝐻₁=0.0 (nontrivial), 𝜀𝐻₁=0.016 (trivial), and 𝜀𝐻₅=62.7218 [19].
