In this paper the authors dealt with the effect of the internal or external pressure on the torsional buckling of a cylindrical shell. Firstly the infinitely long cylinder was considered for the sake of simplicity, neglecting the second order infinitesimals with regards to the small quantities α=h^2/(12a^2), [numerical formula], [numerical formula] and λ=(2πa)/l. In this case the critical stress γ_cr is given by the equation (23), expressing that the critical load as well as the circumferential wave number n after buckling, increases considerably with the internal pressure, and decreases as the external pressure increases, as will be seen in fig.1. The approximate solution for the case of the comparatively short cylinder is given in the equation (24), (25) and (26), by considering the second order terms with respect to λ. The results of the experiment carried out with the celluloid cylinders of 60cm. length with varying radius and thickness were compared with the theoretical results for the case of the short cylinder, and it was confirmed that the buckling stress ranges between 70 and 98% of the theoretical values., 資料番号: SA4146524000}, pages = {347--359}, title = {内壓又は外壓を受ける薄肉圓筒の捩り挫屈}, volume = {19}, year = {1943} }
