摘要

摘要研究了四角形多层复合板的超临界变形，考虑到了与板厚度相称的挠度的几何非线性。用雷利-里兹法求解了位移中的特征值和特征向量问题。研究发现了挠度振幅与轮廓力的关系，并获得了评估任意边界条件下的四边形复合板在失去压缩和剪切稳定性后的应力-应变状态的基本关系。根据各向异性材料的强度标准，确定了失去稳定性后的破坏力。

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.
