Analytical and Experimental Study of Buckling Behavior of Cylindrical Panels

Thin walled structural components such as plates and shells are used in several applications like aerospace, naval, nuclear plant, pressure vessels, mechanical and civil structures due to their high strength to weight ratio. The safety assessment of such structural components required to carefully access the buckling collapse which can be strongly limiting the load with standing capacity. The effects of the length, sector angle on the buckling load of cylindrical panels have been studied experimentally by applying compressive load in the axial direction on the panels using the universal testing machine. Then the cylindrical panel is modeled and analyzed using ANSYS software. The experimental as well as the numerical analysis is repeated for different length, sector angle and loads. The comparison between experimental and simulation results in terms of displacement for various load has discussed.
