Description
<p>This paper presents a numerical procedure to evaluate the buckling of cylindrical structures under pressure load with shell element appropriately. In a situation where the internal and external pressures are subjected to the top and bottom surfaces of cylindrical shells, it is difficult to evaluate the influence of the pressure load of the structure appropriately, due to the complicated loading conditions. Numerical solutions, which are obtained by using conventional shell elements, and analytical solutions are expressed by using the difference between the internal and the external pressures as the external force. On the other hand, solid elements can be employed to model the loading conditions properly, but huge computational cost may be required. In this work, the authors propose a numerical procedure for buckling analysis that evaluates the pressure load appropriately in the framework of the structural elements.</p>
