Abstract: Hemispherical shells subjected to external pressure loading are known to be sensitive to geometric imperfections. Dimple imperfections and their effects on the buckling and postbuckling response of spherical and hemispherical ...

Abstract: Thin-walled cylindrical shell structures are revisited with the objective of increasing the axial load-carrying capacity. By using the postbuckling reserve of rectangular plates, polygonal shells are studied, which combines ...
