Professor of Mechanics, Washington University, St. Louis, Mo. It's easy to construct finite-element models with errors. And it's just as easy to correct them, when you know how. The first step in a ...

Second-order shell elements: Meshing the thin band with secondorder-shell elements produces precise curvilinear geometry. There was a time when the task of building a model for finite-element analysis ...
