Thermal analytical model of bidimensional and unidimensioal structural elements in a space environment. (English) Zbl 0582.73116

When affording interactive thermo-structural problems, a first difficulty is the different modeling approach in the thermal and in the structural field. While in fact bidimensional and unidimensional structural theories are common practive (plates, shells, beams) the same is not true in the thermal field, where the three-dimensional general heat conduction equations are commonly used. In this paper the global analytical thermal conductive-radiative modeling of one- and two-dimensional structural elements is proposed, based on approximations of the temperature field analogous to those made on the displacements in the elastic problems. The resulting models and their use and limitations are presented and discussed.
