摘要：

The article considers a non-axisymmetric deformation and stability of a compressed aircraft shell. Particular attention is paid to modeling contact interaction of shells with transverse shock-absorbing belts. To analyze shell deformations, we used the iteration method, taking into account a nonlinear change in the reaction of the shock-absorbing belt when there are structure displacements. The shell stability equations were discretized by the Bubnov-Galerkin method using Fourier series. The developed model was used to study the deformation mode of constructively and technologically orthotropic shells exposed to local loads of shock-absorbing belts. The simulation models were verified with the results of testing model and actual shells.
