Abstract:
In the case of nonlinear elastic quasitransverse waves in composite media
described by nonlinear hyperbolic equations, we study the nonuniqueness
problem for solutions of a standard self-similar problem such as the problem
of the decay of an arbitrary discontinuity. The system of equations is
supplemented with terms describing dissipation and dispersion whose influence
is manifested in small-scale processes. We construct solutions numerically
and consider self-similar asymptotic approximations of the obtained solution
of the equations with the initial data in the form of a “spreading”
discontinuity for large times. We find the regularities for realizing various
self-similar asymptotic approximations depending on the choice of the initial
conditions including the dependence on the form of the functions determining
the small-scale smoothing of the original discontinuity.
