Basing on this model and using the method of linearized parameters, an algorithm of determination the temperature field and thermal stresses caused by it in a thermosensitive layer is developed. A mathematical model of description the thermoelastic behavior of transversally isotropic thermosensitive bodies under simultaneous centrallysymmetric thermal and force action is formulated. The procedure of its study is proposed, the approximation of temperature dependences of physical-mechanical characteristics of material by piecewise-constant functions of temperature makes the basis of this procedure. Having used the finite element method, an approach to approximate solution of thermoplasticity problems for layered thermosensitive bodies under thermal influences and mechanical loadings is proposed. Using the method of weighted functions and the finite element method, the procedure of construction the algorithms of finding the solutions of thermoviscoelasticity problems for layered arbitrary-shape bodies with spatial coordinates and temperature dependent coefficients is developed. The procedure of determining the one-dimensional thermoelastic state of layered isotropic cylinders with regard for arbitrary dependences on temperature and coordinate of physical -mechanical characteristics of components, is proposed.
