| Abstract: | This paper has applied neumann series expansion to Monte-Carlo stochastic finite elementfor finding the stress of composite convolution structure with stochastic factor, then. the paper has giventhe structure reliability formula according to Monte-Carlo comparison method and Tsai-Hill failure criteri-a. Finally, the paper has found the iteration formula of reliability optimization design for the structure andthe paper has shown an example. |
