| Abstract: | The cylindrical shell stiffened by longitudinal and circumferential stiffeners is widely used in engineering practice and plastic buckling is one of the main collapse forms under uniformly applied external pressure or longitudinal loading. Based on the energy principle and with the Mises yield criterion and plastic strain theory, the plastic buckling of the cylindrical shell is analyzed. A calculating formula for the critical pressure is given and plastic bucklings of the plate, the stiffened cylindrical plate and stiffened cylindrical shell are discussed as special cases. |
