The approach is based on the theory of non-steady-state heat conduction, the theory of plastic non-isothermal flow and calculation schemes of finite element methods. The methods are developed to determine the thermostressed state in structurally nonhomogeneous bodie made of functionally gradient thermoviscoelastic materials under thermal external loads. The methods are based on numerical methods of weighed residues couplead with the finite element method. The method of linearized parameters is adapted concerning the problems of determination the non-stationary thermal state of massive thermosensitive bodies wich make contact along the plane surface. A mathematical model of description the thermosensitive behevior of transversally isotropic-thermosensitive cylindrical bodies under axially symetric plane deformation is offered. The analytical numerical mathods are developed to solve the formulated thermoelasticity problems. The methods are based on utilization the approximation of real temperature dependences of physical mechanical characteristics of material by axially symmetric unit functions. The analytical numerical methods of determination the thermostressed state of a massive piecewice-homogeneus thermosensitive body with plane-parallel material division of interface under the action of surface heat sources are developed.
