 note = {A high precision experiment has been extensively carried out to bridge the gap between the theoretical and experimental buckling loads of spherical caps subjected to external pressure. The details of the forming process of test specimens, experimental arrangements and procedures, and reliable data on the buckling load as well as the deflection and strain distributions obtained are reported. It is shown that the buckling load of perfect spherical caps is close to the so-called classical value, the pre- and postbuckling deformation patterns are axisymmetrical, prebuckling deformation patterns are not fixed but change through the loading and are subject to the geometrical parameter, the number of waves in the meridional direction increases and the so-called boundary layer is formed as the geometrical parameter becomes larger, the membrane state of strains is predominant and load vs. deflection curves are almost linear for large values of the geometrical parameter in the prebuckling state of equilibrium, the deflection of shells is small up to the occurrence of buckling, and hence the small deflection theory will play still an important role in analyzing the stability of spherical caps subjected to external pressure. The detailed discussion on the results seems to contribute to make the mechanism of the buckling of spherical shells clear., 資料番号: SA2400956000},
