A Mixed Element Of The Stokes Problem For Bingham Fluid Anisotropic Triangular Element Analysis

Stokes problem and Bingham fluid problem are discussed in this paper. First, a simplified and stablized mixed element formulation based on bubble function is constructed for Stokes problem, and the convergence analysis is given. Then, an anisotropic triangular element Euler finite element approximation formulation for Bingham fluid problem is proposed, and the same error estimations as the traditional finite element methods are obtained.
