Friction Coefficient Evaluation on Aluminum Alloy Sheet Metal Using Digital Image Correlation

Technical Paper

2018-01-1223

The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes. This research introduces an innovative technique to find the coefficient of friction on a lubricated aluminum sheet metal surface by simulating the industrial manufacturing stamping process while using 3D digital image correlation (3D-DIC) to track the deformation.

Additive Manufacturing in Space:

Did you know that NASA sends up to 7,000 pounds of spare parts to the International Space Station every year? To reduce the clutter, the agency is turning to additive manufacturing – 3D-printing required parts.

How Nanocomposites Support ‘Lightweighting’

Employed in many of today’s automotive fuel tanks and engine parts, the nanoparticles present in nanocomposites have an extremely high surface-to-volume ratio, which improves structural traits like flexibility, strength, flame retardancy, surface appearance, thermal stability, and electrical conductivity.

When Powder Metallurgy Builds a ‘Spaceship’

Powder metallurgy uses tiny particles of metal to build unique parts. See how the 3D-printing company Velo3D used the powder metallurgy process of additive manufacturing to create a microturbine generator roughly the size of a microwave oven.

Rapid Prototyping:

As rapid prototyping and metal 3D printing support the creation of new kinds of automotive components like hubcaps and side air vents, designers need to know that their fabricated parts have been made properly and according to design specifications. The beauty of 3D printing and rapid prototyping? When you’re printing on a layer-by-layer basis, 100 microns at a time, you’re able to see exactly what’s inside the part.

Smart Materials:

When it comes to smart materials, Keith Goossen at the University of Delaware has a newer, cheaper idea for eco-friendly windows and windshields: Liquid. Goossen’s glass contains fluid-activated panels that change from transparent to opaque states – an achievement that he hopes will provide a more affordable, commercial appeal to consumers. The 3D-printed smart materials switch from transparent to reflective a thousand times without degrading.
