摘要：
We study a Morley finite element method for the displacement obstacle problem of clamped Kirchhoff plates on polygonal domains. Error estimates are derived in the energy norm and the L-infinity norm. The performance of the method is illustrated by numerical experiments. (C) 2013 Elsevier B.V. All rights reserved.
