【Abstract】 In this paper a stochastic finite element method is developed for structural reliability analysis of contact problems.Basic formulas are established and a corresponding computational program is compiled.The method works well in the example of a two structure contact system.Convergence is achieved in a few cycles.The method is suitable for large complicated structures and can be extended to 3 D multi structure systems.更多还原
