The buckling of thin walled circular cylindrical shells under combined axial compression and bending

摘要

An experimental investigation of the interaction of combined axial compression and bending stresses on the buckling of cylindrical shells of similar geometry was carried out.The shells tested were manufactured by a copper electro-forming process. This method of fabrication produced thin shells to close geometric tolerances without the usual seams.A total of 16 buckling tests were conducted. The resulting experimental interaction curve indicates that the critical buckling stress increases with increased bending moments.
