| Abstract: | A speedy accurate solution to structural fuzzy finite element equilibriumequations (SFFEEE), by combining the definition of the solution of intervalequations with the mechanical meaning of the structural finite element equilibrium equations (SFEEE),,was put forward. The fuzzification of the SFFEEE,which is discussed in this paper, originates from that of materical property,structural boundary conditions and external loading. The computing quantity ofthis solution is almost equal to that of the general finite element method(GFEM ). |
| Keywords: | finite element equilibrium equatirions fuzzy- numbers interval squations |
