It is unquestionable that the lowering of the buckling load of a circular cylindrical shell is due to the non-linear characteristic of finite displacement theory proposed by v. Karman and Tsien. The author developes further considerations about the essential features of the buckling phenomena. First of all, the fact that the buckled surface is very near to a developable one different from the original cylindrical surface, and therefore the deformation in this case is finite and approximately inextensional, is confirmed both theoretically and experimentally. Based upon this fact, the general buckling and the local buckling with and without the loading spring being analysed from the view-point of energy, it is clarified that the buckling processes are all explained by the energy difference before and after buckling and the energy barrier to be jumped in this case. According to the results, the local buckling is more liable to occur than the general buckling, and in all cases the minimum load, above which the buckling can take place, exists, it being smaller in the case of local buckling than that of general buckling, and further depends on the rigidity of the spring in the case of local buckling.
