Investigation of stressed-deformed state and sensitivity to initial irregularities of underwater vehicle closure bulkheads
Authors examine stressed-deformed state, stability and sensitivity to initial irregularities of two structural options for joining underwater vehicle hull and closure bulkhead. Initial irregularities from ideal shape are entered through first buckling mode. It is demonstrated that elliptic bulkhead having deviations from ideal shape does not work on reception of external pressure just as well effectively as toroid-spherical one
