Buckling and post-buckling behaviour of shallow – nearly flat cylindrical panels under axial compression

Abstract

Abstract. The paper is devoted to buckling problem of axially compressed shallow cylindrical panels. Governing differential equations of the nonlinear theory of shallow cylindrical shells are analytically solved. Critical stresses and equilibrium paths of the panels with small curvatures are analytically studied. The formula of the critical stresses for almost flat, cylindrical panels is derived. The "shallowness" of the panel is given by the parameter ® and formulae are derived for a range of this parameter. The range of values of sectorial angle for these panels is also defined. is a particular structure of this family. The analytic formula of the critical stresses for almost flat, cylindrical panels is presented.The main goal of the study consists in analytical formulation of the critical and post critical states for the family of shallow -almost flat cylindrical panels with consideration of the flat panel.2.

Elastic buckling of a generalized cylindrical sandwich panel under axial compression

“…Malinowski et al [10] discussed the problems of elastic stability and postbuckling behaviour of seven-layered cylindrical shell subjected to uniformly distributed external pressure and simply supported at circular edges. Magnucka-Blandzi and Magnucki [11] studied analytically critical stresses and equilibrium paths of axially compressed shallow cylindrical panels. Fazzolari [12] carried out stability analysis of functionally graded isotropic and sandwich plates by using the advanced hierarchical trigonometric Ritz formulation.…”

Post-Buckling Behaviour of laminated Cylindrical Panels with/without Cut-Outs

“…A few enhancements are introduced as displacement irritation strategies just as power annoyance techniques for following the bifurcation-point-type harmony ways. Bisagni and Cordisco [11] assessed the quality limit of composite cylindrical shells in the post buckling Post-Buckling Behaviour of laminated Cylindrical Panels With/without Cut-Outs Y.Venkata Narayana, P.M. Pranith Bhargav area where the underlying geometric defects and the thickness varieties of the external and inward surfaces are filtered before starting the test to evaluate the geometric blemishes. By utilizing the position control mode, these shell/panels are tried to evaluate their post-buckling quality limit.…”
