Buckling of symmetrically laminated rectangular plates with general boundary conditions – A semi analytical approach

Buckling analysis of laminated composite plates using an efficient C0 FE model

“…Shufrin et al [22] used a semi analytical approach for the buckling analysis of symmetrically laminated rectangular plates with general boundary conditions. Ganapathi et al [37] investigated the free vibration characteristics of simply supported anisotropic composite laminates using analytical approach. Nali et al [14] analyzed buckling behaviour of laminated plates subjected to combined biaxial/shear loading.…”

Semi-analytical buckling analysis of omega stiffened panels under multi-axial loads

“…For instance, combined loads are studied by Chai and Hoon [13] for simplysupported panels, while linearly varying biaxial in-plane loads are accounted for in the formulation of Romeo and Frulla [14]. Similarly, Shufrin et al [15] consider general in-plane conditions by applying the extended method of Kantorovich. The assumption of simply-supported or clamped edges does not account for the finite amount of restraint provided by the stiffeners and, for this reason, can be the source of inaccurate results.…”

A semi-analytical model for deflection analysis of laminated plates with the Newton-Kantorovich-Quadrature method

“…Unlike most of the other semi-analytical methods the accuracy of the solution is independent of the initial chosen functions. This initial function, even if it does not satisfy any of the boundary conditions 39,40 , does not affect the accuracy of the solution. The EKM was applied by Soong 41 to the large deflection analysis of thin rectangular isotropic plates subjected to uniform loading.…”

“…The EKM was applied by Soong 41 to the large deflection analysis of thin rectangular isotropic plates subjected to uniform loading. Some solutions 40,41 used only one-term for expansion yielding of isotropic plates. However, it is showed that one term formulation is not enough to predict the behaviour of anisotropic plates 40 .…”

“…Some solutions 40,41 used only one-term for expansion yielding of isotropic plates. However, it is showed that one term formulation is not enough to predict the behaviour of anisotropic plates 40 . In this study, the NKQ is used to overcome these shortcomings and the model for out-of-plane loading as well.…”
