A new approach to fuzzy finite element analysis Original Research Article

In this paper, a new finite element analysis method for fuzzy structure is proposed by using the information entropy concept. According to this method, the fuzzy variables can be transferred into random variables so that the fuzzy structure can be treated as random structure. When the random variables transferred from fuzzy structure are small, the perturbation finite element method can be used to obtain the mean values and the variances of the structural responses.
