Fig. 7: Energy portion of the IRM.
From: Strong internal resonance in a nonlinear, asymmetric microbeam resonator
The ratio of energy transferred to the IRM to the total energy in both the ERM and IRM is plotted as a function of wF when the parameters of σ1 and αi are varied. The left column (a, b) shows the cases for 1:2 IR, and the right column shows the cases for 2:1 IR. Other parameters used in this analysis are\(\omega _1 = 1,\,\omega _2 = 2,\,\zeta _1 = \zeta _2 = 0.001,\,\left| {\alpha _1} \right| = 0.87,\,\left| {\alpha _2} \right| = 1.75,\,\lambda = 0.1,\left| {\overline {\alpha _1} } \right| = 0.87,\,\left| {\overline {\alpha _2} } \right| = 1.75,\,\overline \lambda = 0.2,\,{\mathrm{and}}\,\sigma _2 = 0.005\)
