Time-Periodic Solutions of Driven-Damped Trimer Granular Crystals

Figure 2

Eigenfrequency spectrum of the trimer granular chain for parameter values given in Table 1 and ms. (a) Spectrum corresponding to (10) for beads. Note that the horizontal dashed black lines correspond to the cut-off frequencies listed in Table 2. (b) Numerically obtained frequencies of the infinite lattice using (14) as a function of the wavenumber ().
