Conventional tests for composite hypotheses in minimum distance models can be unreliable when the relationship between the structural and reduced-form parameters is highly nonlinear. Such nonlinearity ...

Here's when to use linear-static FEA and when to use a nonlinear program. Most engineering problems contain nonlinear effects. Take a paper clip, for example. Push on one end hard enough and the clip ...

Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...

In the relentless drive to build more cost-efficient, less resource-intensive structures, their operating envelopes are expanding resulting in larger deflections and geometric nonlinearities being ...

• Most problems are nonlinear from the get-go. • Simplified load-deflection cases can help explain nonlinear (structural) FEA. Which designers need nonlinear FEA and why? Actually, projects ranging ...
