“…In recent years, analytical and numerical methods have been widely used to predict the buckling of cylindrical shells subjected to hydrostatic pressure. Some researchers have studied the buckling strength of cylindrical shells, focusing on the influence of winding patterns [16] and imperfection [17][18][19]. Li [20] evaluated the critical buckling pressure of pipes under hydrostatic pressure by considering geometrical imperfections.…”

In this study, an analytical solution for the buckling of a composite cylindrical shell subjected to hydrostatic pressure is proposed. The boundary conditions of the composite cylindrical shell are cantilever-like, with one end fixed and the other end connected to a rigid disk. The differential equations are solved using the Galerkin method. The axial displacement of the shell is approximated by the first mode shape of the transverse vibration of the clamped sliding beam. The circumferential displacement and deflection are approximated by the first derivation of the beam function. Based on this solution, an analytical formula enabling prediction of the critical buckling pressure and buckling mode of composite orthotropic cylindrical shells is derived. A finite element analysis and external hydrostatic pressure test are conducted to verify the proposed approach. The efficiency and accuracy of the analytical solution in predicting the critical buckling pressure and buckling mode are demonstrated.

The mechanical properties of composite material exhibit inherent variation with uncertainty. Uncertainties in material properties propagate and result in uncertainties of mechanical performance of structure made of composite material. Polynomial chaos expansion (PCE) is implemented to carry out uncertainty quantification (UQ) and global sensitivity analysis (GSA) of cylinder shell made of composite material for this paper. A case study concerning eigenvalue buckling load of composite cylinder shell is investigated. Design of experiment (DOE) is conducted by utilizing Latin hypercubic sampling. Then data-driven PCE is established and later validated. Statistical moments (mean and standard deviation) and Sobol sensitivity indices of eigenvalue buckling load are obtained respectively. It is found that the PCE can serve as an efficient approach to handle UQ and GSA in engineering applications.

“…One of the most key issues for design and production of composite cylindrical shell structures reflects on a determination of the stress distributions and burst failure load of the structures. The strain distributions of the composite layers at various selected locations were obtained numerically and experimentally (Cho et al , 2019; Zu et al , 2019). An analytical solution of the buckling problem formulated and a post-buckling analysis for a composite cylindrical shell subjected to hydrostatic pressure are presented (Lopatin and Morozov, 2017; Li et al , 2018; Almeida et al , 2018).…”

Purpose The purpose of this paper is to present a finite element analysis (FEA) of filament-wound composites, as well as application of these materials. Design/methodology/approach In this paper, a new finite element method of filament-wound composite is presented. The stress and strain fields in the composite cylinders are analyzed using the ABAQUS software packages for considering the filament undulation and crossover. The paper presented results of buckling load of composite cylinders with different types of filament-winding patterns. Findings The result of the example shows that the stress distributions are uniform along the cylinder length and around the circumference when the analytical approach is based on the conventional FEA. The stress distributions are not uniform along the cylinder length and around the circumference for considering the filament undulation and crossover. The stress units are arranged in a regular geometric pattern around circumference and along the axis of rotation. The analysis of the effect of filament-winding mosaic patterns on the mechanical characteristics of composite cylindrical is presented in the paper. Originality/value The stress and strain fields in the composite cylinders were analyzed for considering the filament undulation and crossover. The buckling load of composite cylinders with different types of filament-winding patterns was presented in this paper.
