Three- and four-wave resonances in the nonlinear quadratic Kelvin lattice
Andrea Pezzi, Tiziana Comito, Miguel D. Bustamante +1
In this paper we investigate analytically and numerically the nonlinear Kelvin lattice, namely a chain of masses and nonlinear springs, as in the alpha-Fermi-Pasta-Ulam-Tsingou (FP…
