Abstract
An analysis of the stability of quadrangular orthotropic composite panels under compression and shear is presented. The stability problem is solved by the Rayleigh–Ritz method in displacements with approximation of the deflection eigenmodes by Krylov functions. An assessment is made of the influence of fastening conditions and the laying pattern of layers of a composite structure on the parameters of the critical behavior of quadrangular panels. The accuracy of the numerical procedures is confirmed by comparison with the results of the exact solution of the main linearized equation of stability theory using the example of an isotropic plate.
