Abstract
Interest in studying of the shell arises from the fifties of twentieth century. Assemblies which contains thin shells, find wide use in the modern engineering especially in ships, aircraft and spacecraft industry. In today’s aerospace and aircraft industries, structural efficiency is the main concern. In this paper the shell vibrations and buckling modes are analyzed by means of numerical methods to clarify qualitatively critical loads and different buckling modes. In our study we focus on the experimental analysis of axial loading for static and buckling analysis for pressure vessel. The modeling and the analysis both are carried out in Ansys 15.0 solver. The analysis provides the stresses for the saddle support & shell near the saddle support due to upset (OBE) and faulted (SSE) seismic load conditions. Furthermore, the results from the simulation are then compared with the KEPIC (Korea Electric Power Industry Code) standards to find the structure integrity of particular unit. Finally, data collected from these simulations results, we conclude that it is safe to manufacture particular pressure vessel with current loading conditions.
