WebJan 1, 2013 · Abstract. We discuss the application of Virtual Elements to linear plate bending problems, in the Kirchhoff–Love formulation. As we shall see, in the Virtual Element environment the treatment of the C 1 -continuity condition is much easier than for traditional Finite Elements. The main difference consists in the fact that traditional Finite ... WebTo prove that the resulting mixed variational formulation is well posed, we use standard Babuška-Brezzi theory with appropriate t-dependent norms [2]. The problem is discretized by standard finite elements [1], and error estimates are proved with constants independent of the plate thickness. roles of a risk manager
