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…
Quantized plastic deformation
N. Perchikov, L. Truskinovsky
In engineering crystal plasticity inelastic mechanisms correspond to tensorial zero-energy valleys in the space of macroscopic strains. The flat nature of such valleys is in contra…
Peristalsis by pulses of activity
Nikolai Gorbushin, Lev Truskinovsky
Peristalsis by actively generated waves of muscle contraction is one of the most fundamental ways of producing motion in living systems. We show that peristalsis can be modeled by…
Supersonic kinks and solitons in active solids
Nikolai Gorbushin, Lev Truskinovsky
To show that steadily propagating nonlinear waves in active matter can be driven internally, we develop a prototypical model of a topological kink moving with a constant supersonic…
