弹性接触问题的对偶混合有限元分析
DUAL MIXED FINITE ELEMENT METHOD FOR CONTACTPROBLEM IN ELASTICITY
【Abstract】 In this paper, based on the mixed variational formulation in [9], a dual mixedvariational formulation for contact problem in elasticity is presented. The existence and uniqueness of the solution of the dual variational problem are discussed,and the error bound O(he3/4) is obtained for Raviart-Thomas (k = 1) elementapproximation.
