چکیده انگلیسی
This study examined the buckling of unstiffened cylindrical shells under external pressure. Six stainless steel cylindrical shell specimens were tested, with a length-to-radius ratio, L/R, ranging from 1 to 7. The wall thickness, diameter, axial length, and geometry of each specimen and the material properties of the corresponding sheets were measured. All cylindrical specimens were subjected to external pressure in a pressure chamber; the buckling load and final collapsed mode were recorded. This paper presents a comparison among theoretical calculations, finite element (FE) results, and experimental data for externally pressurized cylindrical shells. In the numerical calculations, true geometry, average wall thicknesses, and elastic-perfectly plastic modeling were considered. Deviation between theoretical and FE results was 0%to ââ¯22%, and it increased with the length-to-radius ratio. Experimental results are consistent with FE results, with deviation of 2-9%, and final collapsed modes of all shells are consistent.
