Poor FEM explanation
As much as this article represents common views of the finite element method by held by many structural engineers in industry, it has several glaring omissions and shows poor understanding of element properties and connectivity. Midside nodes are added to increase DOF for lagrangian shape functions only, not for elements using legendre shape functions. Nodes do not "drag" the element, but only serve to define connectivity. Contrary to popular belief, displacements ARE defined continuously throughout the entire domain, not just the nodes, and the extraction of displacement within an element is not interpolation! Higher order elements are not treated by this article, in which continuous derivatives can be obtained at any point within any element anywhere in the domain without interpolation. The sin of reduced integration is not mentioned, nor its bad side effects.
