Solitary waves and kinks in FPU lattices with soft-hard-soft trilinear interactions

Anna Vainchtein, Lev Truskinovsky

We consider a version of the classical Hamiltonian Fermi-Pasta-Ulam (FPU) problem with a trilinear force-strain relation of soft-hard-soft type that is in general non-symmetric. In…

When discrete fronts and pulses form a single family: FPU chain with hardening-softening springs

Anna Vainchtein, Lev Truskinovsky

We consider a version of the classical Hamiltonian FPU (Fermi-Pasta-Ulam) problem with nonlinear force-strain relation in which a hardening response is taken over by a softening re…
