Interfacial waves in a finitely strained layered elastic half‐space

Stress Waves in a Microperiodic Layered Elastic Solid Revisited

A one-dimensional pure stress initial boundary value problem of linear elastodynamics for amicroperiodic layered semi-space in which amicrostructural length is taken into account is revisited. Also, the plane stress harmonic waves propagating in a microperiodic layered infinite elastic space are discussed. It is shown that (i) for a particular system of the length and time units the transient s...

Elastic interfacial waves in discrete and continuous media.

Phonon spectra of bicrystals with relaxed grain-boundary structure display a variety of localized modes including long-wavelength acoustic modes. Continuum solutions for localized waves that incorporate atomiclevel elastic properties of the interface via discontinuity relations agree well with the latter modes. In contrast, classical solutions that depend only on bulk elastic properties do not....

Generation of Sh - Type Waves in Layered Anisotropic Elastic Media

A study is made of the generation of SH-type wves at the free surface of a layered anlsotroplc elastic medium due to an impulsive stress discontinuity moving with uniform velocity along the interface of the layered medium. The exact solution for the displacement function is obtained by the Laplace and Fourier transforms combined with the modified Cagnlard method. The numerical results for an im...

Nonlinear waves and wave scattering in layered elastic waveguides

Nonlinear Bulk Elastic Waves in Layered Solid Wave Guides

During the last decade we have performed theoretical investigations and successful experimental research demonstrating the existence and main properties of bulk strain solitary waves in nonlinearly elastic solid wave guides. Following the topic we present preliminary results on strain soliton propagation in layered wave guides made of PMMA. The obvious physical relevance of data on strain solit...
