In this paper we perform finite element analysis of an elastic bar within the context of generalized coupled thermoelasticity. For the description of the elastic behavior of the bar, we adopt the dipolar strain gradient model (Mindlin Form II), including micro-inertia terms. Furthermore, the thermoelastic model used in the present work is consistent with Lord - Shulman theory, i.e. heat conduction with one relaxation time. For the representation of the displacement field we use C~1 interpolation, whereas for the temperature field, C~0 interpolation is adequate. The semi-discrete system of equations is integrated in time, using the Newmark method. The characteristic case of an Ultra-Short-Laser pulse load is solved numerically and the temperature, displacement and stresses are calculated. These results are compared with the uncoupled case.
