Some Exponential Decay Estimates for Thermoelastic Mixtures
This paper concerns the study of time-harmonic vibrations for some classes of homogeneous and isotropic thermoelastic mixtures for which the constitutive coefficients are supposed to satisfy some mild positive definiteness conditions. Introducing some appropriate measures, we evaluate the spatial decay behaviour, when the frequency of harmonic vibrations is lower than a certain critical value.
