Analytical Investigations of Thin Cylindrical Panel Subjected to Under Mechanical Loads

Abstract

structures are utilized in various applications such as pipelines, aerospace and marine structures, large dams, shell roofs, liquid-retaining structures, and cooling towers. One of the key goals in designing these structures is weight reduction, which is essential for improving the overall performance of the system. Using composite materials instead of traditional metallic structures is advantageous because of their higher specific stiffness and strength.

The objective of this project is to perform static, linear buckling, and linear layer analysis to determine the deformation and stress of a thin cylindrical panel, both with and without a hole. The analysis will be carried out on panels made from aluminum alloy 7075, CFRP, and glass fiber reinforced plastic material. The layer stacking method will be used to analyze panels with 3, 6, and 9 layers. The 3D modeling of the panels will be performed using the parametric software CATIA, and the analysis will be carried out using ANSYS software.

The focus of this thesis is to determine the stress on thin cylindrical panels made from both traditional and composite materials, as well as analyzing the effects of layer geometry on panel performance. The results of this study will provide insight into the behavior of these structures under different loading conditions and help optimize their design for improved performance.
