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 ...

A very basic example of this can be noted in certain oldest applications of finite elements. More than 2000 years earlier, geometers were keen on finding out the circumference and area of a circle.

The Cleveland Clinic's Ahmet Erdemir, Ph.D., created this finite element model of the knee joint with representation of the cartilage, menisci and the associated bone structures. An enlarged model ...

Under the Engineering Roadmap, Biocore and FRI—with funding support provided by the NFL—collaborated with partners at the University of Virginia, Wake Forest University School of Medicine, KTH Royal ...

They can complicate analysis because even small assemblies can have bolts, screws, rivets, and weld joints, some with preloads. Still, there are ways to consider fastener reactions, says David Dearth, ...
