NONLINEAR DYNAMIC VARIATIONS IN INTERNAL STRUCTURE OF A COMPLEX LATTICE
Аннотация:
Essentially nonlinearmodel of a crystalline bi-atomic lattice described by coupled nonlinearequations, is considered. Its nonlinear wave solutions account for dynamic variations in an internal structure of the lattice due to an influence of a dynamic loading. Numerical simulations are performed to study evolution of a kink-shaped dynamic variations in an internal structure of the lattice. Special attention is paid on the transition from kink-shaped to bell-shaped variations. It is shown how predictions of the known exact traveling wave solutions may help in understanding and explanation of evolution of localized waves of permanent shape and velocity in numerical solutions.
