Trying to get a highly nonlinear finite element analysis to converge is one of the most difficult and frustrating jobs for a finite element analyst. We tend to assume that we correctly input all of ...

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 ...

Aerospace engineers have long faced a stubborn paradox at the heart of structural design: the best way to find an aircraft panel that meets a set of performance requirements is to search forward ...

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 ...

In 2013, Boeing rolled out the first 787-9 Dreamliner, the newest member of the super-efficient 787 family. In order to power this massive aircraft, Rolls-Royce designed the state of the art Trent ...

(FEA) uses a numerical technique to model and analyze complex structures by solving boundary-value problems. The structure to be analyzed is divided into points (elements) that make a grid called a ...

Finite element analysis, computational fluid dynamics, and multibody dynamics are among the most common simulation techniques. Simulation techniques apply one or more discretization methods to solve ...
