Pidstryhach of the National Academy of Sciences of Ukraine popup.description1 The project is aimed at the development of efficient theoretical-experimental methods of the identification of effective parameters of nonhomogeneous composite materials (the profiles of macroscopic material modules depending on irregular micro-structure, the presence of defects, the boundary irregularity, thin interlayers, and protective coatings), as well as unknown parameters of the thermal and force loadings of structure members implemented by using the nonhomogeneous composite materials. А technique for solving the problems on the identification of the thermal and thermostressed states in multilayer, functionally graded, and thermosensitive solids will be presented under the lack of information about the thermal loading on some segments of the plane surfaces and the supplementary data about the stress-strain state (thermal stresses, strains, or displacements) on the remaining parts of the surface. The obtained theoretical results will be verified by experimental testing. popup.description2   The widespread application of advanced materials (nonhomogeneous, functionally graded, and multilayer structures) and protective coatings along with the nowadays developments in material science endorse the advancement in the identification and analysis of their effective material parameters and prediction of thermomechanical performance. The results are critical for the improvement of the material-processing technologies and ensuring the optimal thermomechanical performance of composite structural members. The efficient methods for the identification of thermomechanical parameters are developed based on the experience gained by both the Ukrainian and Polish counterparts. The project was aimed at the development of efficient theoretical-experimental methods of the identification of effective parameters of nonhomogeneous composite materials, as well as unknown parameters of the thermal and force loadings of structure members implemented by using the nonhomogeneous composite materials. By using the method of the direct integration developed by the Ukrainian counterpart, a technique for solving the problems on the identification of the thermal and thermostressed states in multilayer, functionally graded, and thermosensitive solids is presented under the thermal and force loadings on some segments of the plane surfaces. The solutions of such kind are vital for the formulation and analysis of inverse thermo¬mechanical problems for nonhomogeneous, multilayer, and thermosensitive solids and structures with protective coatings concerning the determination of profiles of material properties and geometrical characteristics of the layers within a composite, which are optimal regarding the performance criteria; they are also essential for solving of the contact problems correctly. The efficient methods are developed for the analysis of the thermomechanical behavior of multilayer structurally inhomogeneous solids with plane-parallel surfaces without a priori imposing functiona Product Description popup.authors Kalyniak Bohdan M.
