| 英文摘要 | We present the Crouzeix-Raviaxt linear nonconforming finite element approximation of the variational inequality resulting from Signorini problem. We show if the displacement field is of H-2 regularity, then the convergence rate can be improved from O(h (3/4)) to quasi-optimal O(h vertical bar log h vertical bar (1/4)) with respect to the energy norm as that of the continuous linear finite element approximation. If stronger but reasonable regularity is available, the convergence rate can be improved to the optimal O(h) as expected by the linear approximation. |
