Abstract

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. 


Keywords: Mixed finite element, Neumann expansion, Random interval finite element, Random fuzzy finite element, Random fuzzy and interval finite element, Taylor expansion
