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, H1 and L2 norms are deduced. The results of numerical experiments confirm the theoretical results obtained.
