| Abstract |
Thin cylindrical shell structures are used in many fields such as structural elements in many branches of engineering: cooling towers, nuclear reactors, silos and steel tanks, etc. They are often subject to a large number of imperfections, due to their manufacturing difficulties. On most of these structures, the defects do not always appear in the same place. Thus, it is necessary to quantify the simultaneous influence of this factor on the critical load. In this work we propose to analyze the effect of different positions of these localized axisymmetric initial imperfections on the critical load of elastic cylindrical shells subjected to axial compression. Numerical analysis is used to evaluate the buckling resistance. According to the results of the parametric study of the perfect shell, the choice of the modeling method, the type and the number of elements necessary to be used in the numerical analysis have a significant impact on the quality of these results. |
