| Abstract: | Computer simulation technique is used to evaluate the fatigue riliability life of structure.An artificial network is adopted to build the corresponding ralation of load levels, damage parameters and material performance and to simulate the changes of material perfor- mance.Applying random dispersed similation method,an analyzing simulation system for rilia- bility material fatigue invalidity has been built. According to sampling of critical distribution about damage accumulation critiria and loading, life distribution is obtained by statistical analy- sis. |
