Problems of definition of thermotension of a thermoelastic core with use of model of the connected thermoelasticity are considered. In this case in the equation of heat conductivity there is the divergence of speed of the movement of material points of the rod, and the elasticity equations contains the temperature gradient. On the basis of generalized functions method the generalized solutions of non-stationary and stationary boundary value problems have been solved at action of the power and thermal sources of various type including ones described singular generalized functions, under various boundary conditions on the ends of a core. Thermoshock waves which arise in such designs at action of impact loads and heat fluxes are considered, conditions on their fronts are received. The uniqueness of the set boundary tasks, including taking into account shock waves has been proved. Regular integral representation of the generalized solutions are given, which give the analytical solution of the tasks. Numerical implementation of solutions of a number of direct, return and semi-return boundary value problems of stationary fluctuations is carried out and results of computer experiments are presented
