Abstract:

In this paper, unconventional quasi-conforming finite element approximation for a fourth order variational inequality with displacement obstacle is considered, the op-timal order of error estimate O(h) is obtained which is as same as that of the conventional finite elements.

Key words: Variational inequality, unconventional quasi-conforming element, optimal er-ror estimate
