| Abstract: | This research was developed on the basis of the buckling subject, which is a part of the national special topic of scientific and technological subject. The simplified model comes from the main vessel of Chinese Fast Breeder Reactor. It is a combined cylindrical shell that consists of several thin-walled cylindrical shells and stiffeners. The finite element programs ANSYS 5.4 and ALGOR FEAS (SUPER SAP 93) were applied to calculate the static buckling of the model under the lateral and axial loads in the normal temperature condition. Some factors such as plasticity, boundary conditions and initial imperfections were considered, and the experimental research carried out. The results of numerical calculation are close to the experimental research. |
