Resonance scattering of elastic waves by an elastic sphere in an elastic medium
The Journal of the Acoustical Society of America, 1984We study elastic wave scattering by an elastic sphere within an elastic matrix under the light of the Resonance Scattering Theory (RST). We consider shear (s) and compressional (p) plane wave incidence on a sphere of radius a, and the four cases of elastic wave scattering that they engender (i.e., pp, ps, sp, and ss).

Somigliana dislocations in an anisotropic elastic medium
International Journal of Engineering Science, 1981Abstract The present paper concerns a Somigliana dislocation that produces a state of generalized plane strain in an infinite anisotropic elastic medium with a circular cylindrical hole. The elastic state is determined when either the displacements or the tractions are prescribed on the boundary of the hole, while the stresses and the elastic ...

Medium effects in deuteron elastic scattering
Journal of Physics G: Nuclear and Particle Physics, 1989Nuclear medium modifications to the deuteron-nucleus folded potential are discussed using a density-dependent effective interaction derived from Brueckner-Hartree-Fock calculations of the optical model potential in nuclear matter. The medium effects generate central and TR type tensor potentials which are found to improve the agreement with ...

Wave attenuation in an elastic medium
Journal of Soviet Mathematics, 1992This article examines the propagation of viscoelastic (elastic) waves in a medium consisting of two layers of finite thickness. It is found that there is a mechanical effect manifest in the monotonic dependence of the damping factor on the parameters of the system.

Wave Propagation in Elastic Medium
2008S wave (Secondary wave) is a propagation of shear deformation that arrives at earthquake observation stations after (second to) the Primary body wave (P wave, see Sect. 4.2). Since S wave generates a significant magnitude of horizontal motion at the ground surface, it is considered to be the most important cause of seismic damage.

Elastic activity of the chiral medium
Journal of Applied Physics, 1999Chiral materials are noncentrosymmetric due to handedness in their microstructures. The elastic field behavior in a chiral medium is readily described herein using the governing equations and constitutive relations for noncentrosymmetric, isotropic micropolar materials.

Inhomogeneous elastic medium with nonlocal interaction
Journal of Applied Mechanics and Technical Physics, 1971In [1] the author examined a macroscopically homogeneous elastic medium of simple structure with spatial dispersion. In that case the assumption of the existence of an elementary unit of length and long-range forces conditioned the nonlocalizability of the theory, and the macroscopic homogeneity was manifested in the invariance of the integral ...

Experiments on Elastic Half-Space Medium
2014The vibration of a rigid foundation resting on the surface of an elastic half-space is in essence a three-dimensional wave propagation problem. Over the years, extensive research has been conducted to obtain analytical and numerical solutions for the dynamics of a rigid foundation with different geometries.

Medium-energy deuteron-carbon elastic scattering
Nuclear Physics, 1965Abstract Optical potentials for deuteron-carbon elastic scattering at 125, 156 and 422 MeV (lab) are obtained in terms of the two-nucleon scattering amplitude and nuclear form factors. The absolute cross-section, vector and tensor polarizations are calculated using complex WKB phase shifts for 50 partial waves. The predicted cross-sections agree well
