“…For perfect cylinders according to equation (43), the number of nonlinear terms applied in classical approach is very less than those in continuum-based approach. Also in classical approach of imperfect cylinders, neglecting some nonlinear terms and selecting other terms from kinematic equation presents a simpler equation than continuum-based approach as [25][26][27]…”

This article introduces a new semi-analytical nonlinear finite element formulation for thin cylinders according to a continuum-based approach. A comparison between the continuum-based approach and the classical approach for the buckling behavior of isotropic and orthotropic perfect cylinders validates the results. The classical approach is defined according to thin shell theories based on the von Karman approximation. A mathematical modeling for geometry imperfection of cylinders is derived according to a continuum-based approach whose results are compared with the results of the classical approach for imperfect cylinders. The influence of neglecting some nonlinear terms in the classical approach for perfect and imperfect cylinders on the buckling path is investigated. In the buckling analysis, two methods, i.e. the perturbation and load disturbance methods, which undertake to switch to the post-buckling path, are compared to each other.

“…Modelling of initial imperfection by the ÿnite-element method has also been described, for instance Kapania and Yang [18] and Saigal et al [19]. As far as the FSM is concerned, Dawe et al [20] and Liu and Lam [21] have extended the method to incorporate the e ect of initial imperfection for the geometrically non-linear analysis of composite laminates.…”

SUMMARYA ÿnite strip procedure has been developed for the post-buckling analysis of composite laminates when subjected to progressive end shortening. The ÿnite strips are developed based on a higher-order shear deformation plate theory and there are nine variables at each nodal line. Initial imperfection expressed in the form of suitable trigonometric function is allowed. Examples including isotropic plates and laminates with arbitrary lay-up arrangement are presented. Numerical results for laminates with and without initial imperfection are used to illustrate the e ect of imperfection.
