Wave propagation in a generalized thermo elastic plate embedded in elastic medium

摘要: In this paper, the wave propagation in a generalized thermo elastic plate embedded an medium (Winkler model) is studied based on Lord-Schulman (LS) and Green-Lindsay (GL) two dimensional theory of elasticity. Two displacement potential functions are introduced to uncouple equations motion. The frequency that include interaction between foundation obtained by traction free boundary conditions using Bessel function solutions. numerical calculations carried out for material Zinc computed non- attenuation coefficient plotted as dispersion curves with thermally insulated isothermal boundaries. characteristics found be more stable realistic presence thermal relaxation times parameter. A comparison results case no effects shows well agreement those membrane theory.
