Problem of Rayleigh Wave Propagation in Thermoelastic Diffusion
In this work, the problem of Rayleigh wave propagation is considered in the context of the theory of thermoelastic diffusion. The formulation is applied to a homogeneous isotropic thermoelastic half space with mass diffusion at the stress free, isothermal, isoconcentrated boundary. Using the potential functions and harmonic wave solution, three coupled dilatational waves and a shear wave is obt...
متن کاملRayleigh-wave Coupling to Atmospheric
THE THEORY of dispersive Rayleigh waves coupled to atmospheric compressional waves is derived for the case of a solid surface layer. Numerical computation of phase and group velocity curves indicates that an additional branch may be introduced to the dispersion curves as a result of air coupling. Amplitudes of waves propagated according to the various branches are briefly discussed. INTRODUCTIO...
متن کاملA Generalized Convolver
A scheme for performing generalized convolutions is presented. A flexible convolver, which runs on standard workstations, has been implemented. It is designed for maximum throughput and flexibility. The implementation incorporates spatio-temporal convolutions with configurable vector combinations. It can handle general multi-linear operations, i.e. tensor operations on multidimensional data of ...
متن کاملApproximation of the Rayleigh wave speed
This brief note describes an asymptotic technique for accurate computation of the Rayleigh wave speed both in compressible isotropic and incompressible orthotropic half-spaces. As opposed to recent publications by Malischewsky and Ogden & Vinh, the Cardan’s formula for solving cubic equations is not used. A variant of Graeffe’s method for finding the moduli of zeros of polynomials is formulated...
متن کاملDynamic crack growth under Rayleigh wave
A nonuniform crack growth problem is considered for a homogeneous isotropic elastic medium subjected to the action of remote oscillatory and static loads. In the case of a plane problem, the former results in Rayleigh waves propagating toward the crack tip. For the antiplane problem the shear waves play a similar role. Under the considered conditions the crack cannot move uniformly, and if the ...
