The model of the equations of two-dimensional coupled problem in thermo-elasticity for a thermally half-space solid whose surface is subjected to a thermal shock is established. The problem is in the context of the Green and Lindsay's generalized thermoelasticity theory with two relaxation times in an isotropic medium with the modulus of elasticity being dependent on the reference temperature. The normal mode analysis is used to obtain the exact expressions for the temperature, the displacement and thermal stress components. The resulting formulation is applied to two kinds of boundary conditions. Numerical results are illustrated graphically for each case considered. Comparison is carried out with the results predicted by the coupled theory and with the case where the modulus of elasticity is independent of temperature.
