Wave Propagation in a Layer of Binary Mixture of Elastic Solids

This paper concentrates on the propagation of waves in a layer of binary mixture of elastic solidssubjected to stress free boundaries. secular equations for the layer corresponding to symmetricand antisymmetric wave modes are derived in completely separate terms. the amplitudes ofdisplacement components and specific loss for both symmetric and antisymmetric modes areobtained. the effect of mixtures on phase velocity, attenuation coefficient, specific loss andamplitude ratios for symmetric and antisymmetric modes is depicted graphically. a particular caseof interest is also deduced from the present investigation.
