Time-Periodic Solutions of Driven-Damped Trimer Granular Crystals

Figure 4

Displacement profiles and corresponding Floquet multipliers of time-periodic solutions obtained at a driving frequency of  kHz for a driving amplitude of (a)  nm, (b)  nm, (c)  nm, and (d)  μm. These solutions correspond to the (A)–(D) labels of Figure 3(b). The lighter masses (i.e., the Steel beads) oscillate (nearly) out-of-phase and are shown as blue diamonds whereas the heavier masses (the Tungsten Carbide ones) are shown as orange squares.
