Abstract

This paper deals with the flow problem of aviscous plastic fluid in a cylindrical pipe. In order toapproximate this problem governed by a variational inequality, we apply the nonconforming mortar finite element method. By using appropriate techniques, we are able to prove the convergence of the method and to obtain the same convergence rate as in the conforming case.
