abstract = {<p style="text-align: justify;">This paper analyzes a nonconforming 5-node quadrilateral transition finite
element for Poisson equation. This element was originally proposed by Choi
and Park [Computers and Structures, 32 (1989), pp. 295–304 and Thin-Walled Structures,
28 (1997), pp. 1–20] for the analysis of Mindlin plates. We show the consistency
error of this element is only&nbsp;$\mathcal{O}(h^{1/2})$ over the transition edges of the quadrilateral
subdivision. By modifying the shape functions with respect to mid-nodes,
we get an improved version of the element for which the consistency error is&nbsp;$\mathcal{O}(h)$.
Numerical examples are provided to verify the theoretical results.</p>},
