The Normal Reflection of Shock Waves

Physical Review, 1947
The problem of the normal reflection of a shock wave is solved by an approximate analytical integration of the hydrodynamical equations. The solution given here leads to nearly the same numerical results as an exact method, based on a graphical integration of the hydrodynamical equations, which has been described by Chandrasekhar. A method of computing

On Wave Reflection in an Elastic Plate

Journal of Applied Mechanics, 1974
A precursor boundary concept is introduced which decouples the stress-free boundary conditions at the parallel surfaces of the plate. The resulting orthogonal eigenfunctions are longitudinal and transverse waves. This property is exploited so as to satisfy stress-free conditions at the edge. The theoretical analysis reveals that the reflected waves are

Wave Reflection by a Periodic Medium

SIAM Journal on Applied Mathematics, 1972
The reflection of waves by a periodic medium is studied in this paper. Assuming steady state waves, the two-dimensional wave equation is reduced to a second order differential equation with periodic coefficients, which is analogous to the one-dimensional Mathieu equation. This governing equation is studied by perturbation methods. Both conventional and

Reflection of Waves by an Inhomogeneous Medium

Physical Review, 1954
A new approximate solution is given for the general linear second-order differential equation which is especially appropriate in treating the reflection of waves by an inhomogeneous medium. The well-known approximations to a fundamental pair of solutions made by Liouville, Rayleigh, and Jeffreys, which suffer from singularities at the zeros of a ...

The reflection and transmission of shock waves I: The reflection of a detonation wave at a boundary

Philosophical Magazine, 1957
Abstract It is shown that, for a shock wave advancing through any physically real barotropic medium, the nature of the reflected wave is uniquely determined by the relative shock impedances of the medium through which the incident wave passes and the medium upon which it falls. A simple criterion is found for determining the nature of the reflection of

Reflection of magnetoacoustic waves

Journal of Applied Mechanics and Technical Physics, 1970
The problem of the reflection of magnetoacoustic waves at the boundary dividing an elastic medium from a fluid medium with infinite conductivity in the presence of an arbitrary constant magnetic field was treated in [1]. In writing down the boundary conditions the continuity of the tangential component of the magnetic field was used.

Reflection of Shock Waves

1994
The study of reflection of shock waves from rigid boundaries has been a subject of considerable interest. Reflection phenomenon can be divided into three sub-heads.
