Buckling analysis of rectangular plates with centered cut-out subjected to in-plane two directions under different boundary conditions

Abstract

In this research, buckling behavior of rectangular plates of symmetric and antisymmetric laminated composite having centered circular hole under in-plane static loadings is analyzed with the aid of first shear deformation theory and the finite element method is used to find critical loads. The presence of hole may cause redistribution of stresses in plates with reduction of stability. The aim of the current paper is to find critical buckling load. The loads depend on many parameters like geometric aspect ratios (a/b) and (d/b), plate thickness (t), diameter of the circular hole (d), orientation of ply and boundary conditions. Numerical simulations for various boundary conditions obtained are shown in tables and graphical forms and compared with each other.

“…J. E. Bahaoui, L. L. Bakkali, and A. Khamlichi [13] numerically investigated the effect of imperfections on shell buckling strength on thin elastic circular cylindrical shells using the Abaqus software package [13]. A. E. Bouhmidi, M. Rougui, and O. Mouhat [14] studied the buckling of symmetrically and anti-symmetrically composite plates with a circular hole. The plate deformation theory and the variational energy method, supported by the finite element method, were applied to find critical loads [14].…”
