The harmonic vibrations method is used to obtain the displacement components, stress tensor and temperature distribution in the considerd physical domain with comparison with the two theories. The obtained analytic solution of the problem is applied for special cases for which the effect of two temperatures is studied. The conductive and dynamical temperatures as well as stress and strain components are shown graphically for a suitable material. Some comparisons are also introduced in the absence and in the presence of gravity, and two-temperature parameter. The differences in the obtained results between the two theories are considered.}, type={Article}, title={Wave propagation in 2D between two elastic media in contact in theory of generalized two-temperature thermoelasticity with gravity effect}, URL={http://www.czasopisma.pan.pl/Content/116178/PDF/09_paper.pdf}, doi={10.24425/ather.2020.132956}, keywords={Generalized thermoelasticity, surface waves, Two temperature, Lord-Şhulman theory, Influence of gravity}, }
