The subject of the study is methods of analysis of linear and nonlinear boundary-value problems of mechanical engineering, which describe the behavior of power thin-walled structures. The purpose of the work is to increase the accuracy, reliability and efficiency of determining the vector fields of displacements, tensor fields of stresses and strains, critical parameters of stability, frequencies of natural and parametric oscillations, limit loads (bearing capacity) of power structures of aerospace engineering. The basis of the research is the approaches of general theory of boundary value problems, functional analysis, variational principles and methods of mechanics of deformed solids, numerical methods of linear algebra.
