| Abstract: | Critical load of cylindrical shell with crack is studied on the basis of dynamical FEM. Two kinds of crack lengths and ten kinds of crack directions are examined. The analysis of computation results shows that the crack directions have a great effect on the axial pressure buckling intensity. |
