ANew Solution to Structural Fuzzy Finite Element Equations Based onMonosource Fuzziness

Considering that a fuzzy number can be decomposed into a real number and a unit fuzzy number under the monosource of fuzziness, a newmethod to solve fuzzy finite element equations is presented. The procedure of this method in solving a fuzzy finite element equation is firstly to separate the fuzzy factors from the problem, then to solve the finite element equation left, and finally to deal with the result with fuzzy factors. Thus, the method not only can greatly reduce calculatingwork in transforming the fuzzy set into the natural number set, but also can be much greatly convenient for engineers and researchers to study and analyze the structures.
