In 1966, two Brazilian men were found dead on Vintém Hill under bizarre circumstances that continue to perplex investigators and conspiracy theorists alike. Lying side by side, their bodies were discovered wearing matching lead masks—shields with no eyeholes—alongside cryptic notes. Were they victims of a cult ritual, a failed experiment, or something even more otherworldly?

A short introduction to this album.
F
Finite Element Analysis - for iPad/Mac/PC
How final element analysis is used to get maximum performance out of Formula 1 cars, focussing on two components: the wheel hub and the 'tub'.
F
Finite Element Analysis - for iPad/Mac/PC
The first step in final element analysis is to understand precisely what a component does and how it interacts with other elements. Lewis Butler from Red Bull Racing reveals the role of the hub in F1 car design.
The second step is to analyse the stresses and strains that the component will be subject to. Lewis Butler from Red Bull and Ray Martin from the OU explain how the hub has to be able to cope with massive external loads.

The third step is to consider the wheel hub's boundary conditions and how these interact with the external stresses on the wheel hub.
F
Finite Element Analysis - for iPad/Mac/PC
Step 4 is to create a solid CAD model of the hub. This is a complex process which involves a series of assumptions and simplifications which need to be taken into account to get a true picture of the hub's behaviour.
F

Step 5 is to create a mesh model of the hub, with 72 000 elements. The mesh density is at its greatest in areas of particular interest.
F
Finite Element Analysis - for iPad/Mac/PC
Step 6 is to input the various stresses and loads that the hub will have to cope with, and use a computer programme to solve the model. Today this can be done quickly and reliably though it still needs a lot of interpretation by the engineers and designers.
F
Finite Element Analysis - for iPad/Mac/PC
The final step is to put the lessons learned through FEA and use them to manufacture new improved components which increase your chance of success.
F
Finite Element Analysis - for iPad/Mac/PC
The same FEA process that was used to redesign a car's hub can also be used to improve its 'tub', otherwise known as its chassis.
F
Finite Element Analysis - for iPad/Mac/PC
The tub, or chassis, is the largest component of a car. It cocoons the driver and all the major components, from the engine to the car's suspension, are mounted in the tub.
F
Finite Element Analysis - for iPad/Mac/PC
The stiffer the tub, the more responsive and better performing the car. A torsion test can be used to assess and then improve the tub's characteristics.
The engine and the other components attached to the tub set relatively straightforward boundary conditions.
F
Finite Element Analysis - for iPad/Mac/PC
Lewis Butler from Red Bull Racing explains how the design and the construction of the tub makes for a very complicated computer model.
F
Finite Element Analysis - for iPad/Mac/PC
Lewis Butler explains why and how he builds a model of half of the tub. Because of its complexity, much time and computing power is needed to solve the model.
