Classical generalized problems are constructed for the initial-boundary value problems obtained as a result of mathematical modeling. Mathematical models for identification of various parameters of problems of elastic-deformed and thermoelastic state of multicomponent bodies with layers and folded cylinders at non-stationary temperature field are constructed. Based on the results of the theory of optimal state control of multicomponent distributed systems, explicit expressions of gradients of residual functionals are obtained for the construction of methods and algorithms for identifying parameters by gradient methods. Numerous experiments have been carried out, which confirm the theoretical results. The introduction of research results in relevant information technologies will allow a systematic analysis of the dynamics of elastic-deformed and thermoelastic state in a non-stationary temperature field in complex modern objects for various purposes, determine the characteristics of new materials, solve problems of continuing resources of studied objects.
