Hence, inflatable structural components become unbalanced under static loading. In this case, change in the character of deformation is indicated by buckling load at initial instant. Generally, significant load for analysis is the critical buckling load which is obtained at an instant when the material fails plastically or the structure collapses. In this research work, an inflatable cylinder is considered for numerical analysis. The cylinder is constrained as hinged at one end and simply supported at the other for studying buckling parameter. This study presents a numerical model made by using the commercial solver ABAQUS and solved for the same pattern of work, lastly, results obtained by both forms of analysis is to be correlated and inference is to be determined. Keywords: Inflatable Cylinder; Buckling; ABAQUS I. INTRODUCTION In this paper, the buckling analysis of the beam is carried out using experimental setup. The result obtained by experimentation matched with the analytical results closely. It is a well-known fact that, due to unrealistic boundary conditions and unavoidable errors, the exact match between simulation results, analytical solution and experimental results could not be achieved. Therefore, an experimental model is set up and the detailed analysis of the same is performed. The comparison of experimental and analytical results will give a detailed insight into the behavior of inflatable beams. Finally, buckling load value obtained experimentally is used for finite element analysis and von mises stress is determined for inflatable cylinder. II.
