THE EFFECT OF PURE SHEAR ON THE REFLECTION OF PLANE WAVES AT THE BOUNDARY OF AN ELASTIC HALF-SPACE
This paper is concerned with the effect of pure shear on the reflection from a plane boundary of infinitesimal plane waves propagating in a half-space of incompressible isotropic elastic material. For a special class of constitutive laws it is shown that an incident plane harmonic wave propagating in the considered plane gives rise to a surface wave in addition to a reflected wave (with angle o...
متن کاملReflection and Transmission of Plane Waves at Micropolar Piezothermoelastic Solids
The present investigation analysis a problem of reflection and transmission at an interface of two micropolar orthotropic piezothermoelastic media. The basic equations and constitutive relations for micropolar orthotropic piezothermoelastic media for G-L theory are derived. The expressions for amplitude ratios corresponding to reflected and transmitted waves are derived analytically. The eff...
متن کاملOblique Shock Waves and Shock Reflection ∗ †
Oblique and conical shock waves are generated as solid projectile flies supersonically, or as a planar shock wave is reflected along a ramp. We study the stability of oblique shock waves for full Euler system of equations in gas-dynamics. The stability criterion is applied to the discussion of regular shock reflection phenomena and the transition of a regular shock reflection to Mach reflection.
متن کاملCaustics of weak shock waves
The caustics of weak shock waves are studied through matched asymptotic expansions. It is shown that these caustics are thinner and more intense than those of smooth waves with a comparable amplitude. This difference in scalings solves a paradox that would have the caustics of weak shock waves behave linearly, even though linear theory for discontinuous fronts predicts infinite amplitudes near ...
متن کاملFocusing of weak shock waves and the von Neumann paradox of oblique shock reflection
Some phenomena involving intersection of weak shock waves at small angles are considered: the focusing of curved fronts at a&es, the transition between regular and irregular reflection of oblique shock waves on rigid walls and the diffraction patterns arising behind obstacles. The intersection of three shock waves plays a central role in most of these phenomena, giving rise to the von Neumann p...
