The force is acting along the interface of isotropic generalized thermoelastic medium and the elastic layer of depth h. The normal mode analysis is used to obtain the exact expressions for displacement components, force stress and temperature distribution. The variations of the considered variables through the horizontal distance are illustrated graphically. The results are discussed and depicted graphically. http://pubs.sciepub.com/jmsa/2/1/3/jmsa-2-1-3.pdf Dual-phase-lag model thermoelasticity temperature distribution normal-mode
