Research and optimization on this basis of their thermal and stress-strain states. Mathematical models of thermomechanical behavior of structurally inhomogeneous bodies (layered, made of functionally gradient materials, with thin inhomogeneities such as inclusions or cracks), in particular, shells and plates, under the action of thermal and force loads, taking into account the processes of thermal radiation transfer and thermal sensitivity of physical and mechanical characteristics and the methodology for its optimization under complex loads, one of which is thermal radiation, have been developed. New computer-oriented algorithms and methods of analytical-numerical and numerical solution of the formulated problems on thermal and stress states of layered bodies and limit equilibrium of bodies with defects (in particular, with filamentous inclusions) were developed, containing nonlinearities due to radiation heat transfer, peculiarities of mechanical behavior of materials of structural elements and their thermal sensitivity, as well as containing the generalized conditions of heat transfer (in particular, with an approximate account of an interlayer or coating). The qualitative and quantitative regularities of thermomechanical behavior of bodies, the influence of combined thermal and power loads on it under various parameters, of specifics of radiative, thermal, and mechanical properties of materials of structural elements (in particular, different transparency or functionally gradientness) are investigat Product Description popup.authors Ivasko Roman O.
