Abstract

The paper considers the buckling of complete spherical shells. The main purpose could be, as a basis for real design, to find the lower critical load. Three scientists developed the idea that the buckled shape of the shell is the isometrically transformed shape of the original shell surface. Applying this idea using rotationally symmetric buckled shape the lower critical load can be calculated fairly easily for spherical shells. In reality the buckled shape has rather discrete rotation symmetry. Considering this kind of buckled shape is the main task of our research. Some preliminary results related to this buckling form will be presented here.
