The linear governing equations of a micropolar thermoelastic medium without energy dissipation are solved for surface wave solutions. The appropriate solutions satisfying the radiation conditions are applied to the required boundary conditions at the free surface of the half-space of the medium. | Rayleigh wave in a micropolar thermoelastic medium without energy dissipation Engineering Solid Mechanics 4 2016 11-16 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Rayleigh wave in a micropolar thermoelastic medium without energy dissipation Baljeet Singha Ritu Sindhub and Jagdish Singhb a Department of Mathematics Post Graduate Government College Sector-11 Chandigarh - 160 011 India b Department of Mathematics .

Introduction The dynamical theory of thermoelasticity investigates the interaction between thermal and mechanical fields in solid bodies and plays important role in various engineering fields. The generalized theories of thermoelasticity which admit a finite speed of thermal signals second sound have aroused much interest during last four decades. For instance Lord and Shulman 1967 by incorporating a flux- rate term into Fourier s law of heat conduction formulated a generalized theory which involves a hyperbolic heat transport equation admitting finite speed for thermal signals. Green and Lindsay 1972 by including temperature rate among the constitutive variables .
