“…Mohammed et al 18 considered the buckling of thin cylindrical composite panel with oval cutout using ABAQUS software. Kocabas and Yilmaz 19 investigated numerically and experimentally the elasto-plastic buckling behavior of semi-cylindrical shells having elastic edge restraints and subjected to a central radial load. Reddy and Sai Ram 20 used the FEM to consider the buckling behavior of functionally graded carbon nanotube reinforced composite cylindrical shell panels.…”

Buckling of composite stiffened cylindrical shell panels having cutout is analyzed using the finite element approach. Shell panel and stiffeners are modeled using first-order shear deformation theory and considering displacement compatibility at the stiffener-panel interface. Convergence and validation studies are conducted to establish the accuracy of the present approach. An attempt is made to maximize the uniaxial and biaxial buckling loads by varying the lamination, boundary conditions, load position, depth of stiffeners, and their arrangements. Parametric studies show that buckling load and mode shapes depend on the size of cutout, ratio of shell width to thickness, degree of orthotropy, and fiber orientation angle. The parametric variations considered here may help the practicing engineers to have an elaborate design aid for improving the buckling strength of such shell panels.

The present study investigates elastic buckling behavior of open-section shell segments under action of a central radial load. A design parameter is expressed to characterize the influence of fillet radius on load-bearing capacity. A reduction factor equation is developed as a multivariate function of shell parameters, which evaluates the amount of decrease in load-bearing capacity of the structure caused by the corner fillet. In addition, an expression to predict limit load of the shell structure under clamped end conditions is introduced. Furthermore, a parametric study is performed to reveal the influence of fillet radius and radius-to-thickness ratio on the limit load as well as deformation patterns of the open-section shells. Results show that corner fillets have a significant effect on the limit load of the open-section shell segments under in-plane loading.
