Keywords: deformation, nonlinearity, plate, finite element

The considerable panel part of modern airframes gets the supercritical nonlinear deformation. The practical need of the nonlinear analysis is admitted. The information about the developed finite elements with high convergence for the nonlinear analysis and about some results of their application for strength and technological problem solving is given.
