Abstract:

Fatigue is a potential failure mode of submarine pressure hulls. Stress analysis will be conducted on a new Type 471 submarine from Australia which will be constructed from a new high strength steel. The higher design loadings made possible by the higher strength make fatigue an even more significant consideration than in other designs. The stress analysis of submarine pressure hulls under hydrostatic loading is reviewed. The main emphasis is on analytical methods of calculation as opposed to numerical e.g. finite element methods, and on the calculations of the fatigue loading rather than the calculation of buckling pressure. Because of the emphasis on fatigue, stress concentrations, residual stresses and the interaction between residual and applied stresses are considered.
