Using the methods of mechanics, applied mathematics and electrodynamics of continuum, nonequilibrium thermodynamics, physical materials science , theory of optimal control we have developed: mathematical models and (having applied the analytical and numerical approaches) the procedures of study the mechanical behavior of bodies with temperature-dependent characteristics at complex heat exchange; the procedures of construction the solutions to direct and inverse elasticity and thermoelasticity problems for inhomogeneous bodies; the procedures of description the thermoelastic state of semitransparent bodies with cavities at thermal radiation considering spectral dependences of radiation characteristics; mathematical models and procedures of study the thermostressed state of irradiated plane-layered bodies (multilayer plates) and have found the regularities of their thermomechanical behavior depending on radiation properties of component materials, their thickness and temperature of the radiation source; mathematical models and procedures of numerical modeling the stress-strain state of structure elements of power-generating plant with damages under real conditions of its operation; the theory and methods of optimization the stress-strain state of piecewise- homogeneous bodies, shells in particular, considering thermosensitivity and locality of restrictions; mathematical model and procedure of determination thermal and thermostressed states of inhomogeneous cylindrical bodies having incomplete information about thermal loading. The solutions of new nonclassical problems on determination and optimization the parameters which describe the thermostressed state of particular structure elements, granting the above factors, have been found and studied. The results of investigations can be used at elaborating the rational regimes of processing and exploitation for structurally inhomogeneous element of designs in the presence of power, thermal and electromagnetic action.
