Abstract:

In this paper, some new methods of error estimates for nonconforming plate element is given according to the properties of divergence space. The error estimate of energy norm and L2(Ω) norm is proved. Compared with the former methods, it is more direct and convenient,  and it also obtains the order required.

Key words: Nonconforming element,  Error estimates,  Plate-bending problem
