主 题：nonconforming finite element tree-dimension fourth order elliptic equation
摘 要：In this paper,the 16-parameter nonconforming tetrahedral element which has an energy-orthogonal shape function space is presented for the discretization of fourth order elliptic partial differential operators in three spatial *** newly constructed element is proved to be convergent for a model biharmonic equation.
