A 3RD-ORDER MIXED FINITE-ELEMENT METHOD FOR THE NUMERICAL-SOLUTION OF THE BIHARMONIC PROBLEM

[摘要] This paper is devoted to the introduction of a mixed finite element for the solution of the biharmonic problem. We prove optimal rate of convergence for the element. The mixed approach allows the simultaneous approximation of both displacement and tensor of its second derivatives.
