Abstract
In this paper, we consider canonical von Kármán equations that describe the bending of thin elastic plates defined on polygonal domains. A conforming finite element method is employed to approximate the displacement and Airy stress functions. Optimal order error estimates in energy, H 1 and L 2 norms are deduced. The results of numerical experiments confirm the theoretical results obtained.
