The parameters of the structure contain random variables and interval
variables. The Taylor expansion method and Neumann expansion method of random
interval finite element are proposed. The parameters of the structure are random and
fuzzy. Taylor expansion method and Neumann expansion method of the random
fuzzy finite element are illustrated. The parameters of the structure are random, fuzzy
and non-probabilistic. The mixed finite element calculation should be carried out
using Taylor expansion and Neumann expansion.
