The fundamental equations of plane strain problems in generalised thermoelasticity with one relaxation time parameter including the heat source have been written in the form of a vector matrix differential equation. Integral transform techniques are adopted, namely: the Laplace transform for the time variable and the exponential Fourier transform for one of the space variables. Exact expressions for the temperature distribution, thermal stresses and displacement components are obtained in the Laplace-Fourier transform domain. A numerical approach is implemented for the inversion of both transforms in order to obtain the solution in physical domain. Finally, numerical computations of the stresses and temperature have been made and represented graphically (for different values of time t and relaxation time parameter t as shown in the figures).
