文摘
- •
Destabilization of intrinsic localized modes (ILMs) by parametric excitation is investigated for FPU, NKG, and mixed lattices.
- •
Frequency and amplitude of parametric excitation is determined based on characteristic multipliers of ILMs.
- •
Unstable regions for the mixed lattice case show very similar shape to those of the Mathieu equation.
- •
ILMs become unstable by causing parametric resonance.
