| Abstract: | The application of the reliability theory and method in structure analysis and design of submarine is investigated. Formula and methods derived by full and approximate probabilistic method are presented. Three criteria for reliability optimum design are given, namely, (a) making the structure volume a minimum when the probability of failure is given; (b) making pf a minimum or R a maximum when the maximum permissible structure volume is given; (c) obtaining the best satisfaction when both constraints on reliability and volume are to be satisfied. Numerical results show that the investigation is a success. |
