“…Cheung [26] developed the finite strip method to study the behaviour of the structural elements. Finite strip method was employed by Amoushahi and Azhari [29] to predict local, distortional, and lateral buckling of the composite fiber reinforced plastic (FRP) structural plates.

A semi-analytical fully discretised finite strip method is developed to investigate the prebuckling and local buckling of viscoelastic plates with different boundary conditions subjected to time-dependent loading. The mechanical properties of the material are considered to be linear viscoelastic by expressing the relaxation modulus in terms of Prony series. The fully discretised finite strip equations are developed using a two point recurrence formulation which leads to a computationally superior formulation. Time history of maximum deflection of plates with different end conditions is calculated. The effects of thickness, length of plate and transverse loading on critical buckling load are also studied.

“…The mth-order global-local theory satisfying the free surface conditions and the geometric and transverse shear continuity conditions at interface was presented using the power series expansion of displacement components along thickness as well as the double-superposition hypothesis proposed by Li and Liu [10]. Amoushahi and Azhari [11] employed the complex finite strip method to predict local, distortional, and lateral instabilities of composite fiber reinforced plastic (FRP) structural plates where the plates were subjected to a combination of longitudinal compression, longitudinal in-plane bending, or shear stress. A sinusoidal function was assumed in the longitudinal direction while the critical stress and critical moment of I-shaped and box and channel sections under bending and uniform loading were obtained by solving an eigenvalue problem.…”

This article presents the stability analysis of reinforced viscoelastic composite plates subjected to in-plane loading using a finite strip method. The equations governing the stiffness and geometry matrices of moderately thick rectangular plates in the time domain are presented using higher-order shear deformation theory and effective moduli method. The critical buckling loads of viscoelastic plates are determined through solving the eigenvalue problems related to the global stiffness and geometry matrices. The accuracy of the developed model is verified against the results reported elsewhere while a comprehensive parametric study is presented to show the effects of different variables on local buckling coefficients.

“…Torkamani et al [11] solved elastic flexural-torsional buckling analysis of plane structures using energy equations. New solutions to flexuraltorsional buckling problems have been presented using computer-aided methods such as the finite strip method (FSM) [9,24] and the finite element method (FEM) [1,4,6,18,23,29]. Due to easier definition of boundary conditions, FEM is the one of the most popular numerical methods.…”

The flexural-torsional buckling of thin-walled pultruded fiber-reinforced plastic (FRP) members composed of unstiffened, stiffened cruciform-and I-shaped sections under uniform compressive loads was investigated using finite element methods (FEM). As the basic method, an eigenvalue solution using the minimum potential energy method was utilized to obtain the critical buckling stress and buckling mode shapes. FEM results were compared with the closed-form solutions and literature results. Furthermore, a parametric study was carried out to investigate the different cross-section geometries and span lengths on the critical buckling stresses and buckling mode shapes, that is, flexural, torsional, or mixed buckling.
