  • Axial compression on stainless steel spherical shells was performed under different loading styles by quasi-static tests, and the deformation energy of spherical shell was calculated.The stress distribution was observed through the photo elastic experiment so as to analyze the deformation model of hemispherical shell under static load.It can be seen that, the maximum stress occur near the loading point at the beginning, and extends outward in a circular form with the compression depth increases, eventually larger stresses distribute near polygon vertex, loading point and the region between them.It's also simulated by ABAQUS software to analysis the influence of loading method and hemispherical shell size on deformation mode.The result shows:The ability to resist deformation of spherical shell decreases along with the R/t increase; under flat nosed compression, the contact force of spherical shell decreases after reaching the peak, but it doesn't under other loadings; the increasing ratio of contact force is only related with thickness, but not with radius.
