Based on resolution of interval Numbers and fuzzy resolution theorem, we develop a method of solving the structural fuzzy finite element equilibrium equations.
利用区间数的分解和模糊分解定理，研究了一种结构模糊有限元平衡方程的求解方法。
But if the surface layer is considered, the traditional finite element methods can not be used, since the ill-condition of structural equilibrium equations produce numerical difficulties.
但是，如果考虑表面层，常规有限元法由于结构平衡方程病态而导致数值上的困难。
