| Abstract: | A triangular displacement element of thin plate, in which the formulation is as simple as that of BCIZ element, is devoloped in this paper. The proposed element can pass the patch test for arbitrary grid subdivision and converges to the precise solution. High accuracy is obtained with fewer degrees of freedom. |
