Stress waves in a microperiodic layered elastic solid revisited

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...

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...

Stress Waves in a Generalized Thermo Elastic Polygonal Plate of Inner and Outer Cross Sections

The stress wave propagation in a generalized thermoelastic polygonal plate of inner and outer cross sections is studied using the Fourier expansion collocation method. The wave equation of motion based on two-dimensional theory of elasticity is applied under the plane strain assumption of generalized thermoelastic plate of polygonal shape, composed of homogeneous isotropic material.  The freque...

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...
