“…The numerical analysis of the problems of lowering the level of thermal stresses by the proper choice of dependences of the characteristics of composite materials on two coordinates was carried out in [11]. The problems of determination of the speed-optimal modes of heating of bodies with constrains imposed either on temperature or on stresses were considered in [4,18]. In addition, the problem of identification of the thermal stressed state of bodies with incomplete information about the conditions of heating was also analyzed in these works.…”

“…It is clear that the adequacy of theoretical investigations of the thermoelastic behavior of these structural elements is strongly affected by neglecting inhomogeneities, including, in particular, their functionally graded nature (the presence of layers in elements) and the temperature dependences (thermal sensitivity) of physicomechanical characteristics (PMC) of materials. The analysis of the state of investigations of the thermomechanical behavior of bodies of this kind shows that taking into account the entire collection of important factors (including the geometry of body, inhomogeneity of its structure, thermal sensitivity of the PMC of materials, and thermal and force actions) leads to mathematical problems whose solution, even with the help of numerical methods, is connected with significant difficulties and requires specially developed algorithms or substantial adaptation of the existing procedures [2,4,5,12,13,15]. However, in the engineering practice, it is preferable to use relatively simple numerical-analytic relations and algorithms, which enable one to study the thermomechanical behavior of the object with predicted reliability.…”

“…In this case, the mathematical model for the determination of the unknown thermal state of a solid calls for the formulation of an inverse thermoelasticity problem. [27][28][29] A problem on the identification of the heat flux on the inner circumference of a long hollow cylinder was considered by Blanc and Raynaud [26] under the supplementary information about the temperature and strains on the outer periphery. Comparing the experimental and numerical results, the efficiency of the presented technique was illustrated and the advantages of such formulation over the one based on the inverse heat-conduction problem were clearly shown.…”
