摘要
文章基于非协调元理论，建立三维块体单元的非协调元列式，导出消除单元内参后的单元应变矩阵、单元刚度矩阵的显式．避免了一般内参型非协调元必须的内参静力凝聚处理，简化了计算过程，提高了计算效率。
Based on the theory of incompalible elements, this paper established incompalible element rank formula of three-dimensional block element, deduced the expressing formula of the element strain matrix and element stiffness matrix which were eliminate the internal paremeters.
