The subject of the study is the methods of analysis of linear and nonlinear boundary value problems of the mechanics of a deformed solid, which describe the behavior of thin-walled power 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 research is based on the approaches of the general theory of boundary value problems, functional analysis, variational principles and methods of the mechanics of a deformed solid body, numerical methods of linear algebra. Analyzed, made conclusions, and provided recommendations regarding the further operation of parachute systems, which as a result of the expiry date have reduced mechanical characteristics For geometrically nonlinear plate models, weak solutions are constructed, their convergence and accuracy are investigated, and a number of practically important examples of calculations are given.
