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 ...

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 ...

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 ...

(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 ...

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 ...

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 ...
