Finite element analysis (FEA) is a cornerstone of modern computational mechanics, enabling the simulation of complex physical systems by subdividing a continuum into discrete finite elements. This ...

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 ...

When surgeons remove an aggressive bone tumor from the pelvis, saving a patient's life can mean sacrificing a large portion of the spine and hip. Putting that fragile structure back together in a way ...
