Nonlinear Deformation and Load-Loading Capacity of Quadrangular Composite Panels
Abstract
The supercritical deformation of quadrangular multilayer composite panels has been studied, taking into account geometric nonlinearity for deflections commensurate with the thickness of the plate. The solution of the problem on eigenvalues and eigenvectors is carried out in displacements by the Rayleigh–Ritz method. The dependences of the deflection amplitude on the contour forces were found, and basic relations were obtained for assessing the stress–strain state of composite quadrangular panels with arbitrary boundary conditions after loss of stability in compression and shear. Based on the strength criteria of anisotropic materials, the destructive forces after loss of stability are determined.
