Strain Measurement using High-Speed Data Acquisition Systems in a Split-Hopkinson Bar Application

            Dynamic material testing, such as in a Split-Hopkinson bar test, requires high-speed data acquisition (DAQ) and sensors with enough bandwidth to capture these dynamic impulses. In this tech talk presentation, HBM, manufacturer of strain gauges, load cells, torque transducers, data acquisition systems and software, will give an introduction in Split-Hopkinson bar tests as well as discuss the required data acquisition systems for this type of testing.

Coming Soon - Carbon Fiber Reinforced Polymers - How Fiber Lengths and Loading Define the Achievable Properties and Dictate the Manufacturing Techniques

The Webinar will look at the properties of thermoplastic composites. Focusing mainly on carbon-fiber filled composites, we will show how the geometry of the filler, as well as the amount of filler, affects the properties of the finished article. The filler properties also generally determine the available manufacturing techniques that can be used.

Will "Flying Cars" Become a Reality?

A Boston-based aerospace company Terrafugia announced last year that it began work on its TF-6, a four-seat hybrid electric car that can do vertical take-offs and landings. The vehicle has foldable wings, cruises at 100 miles per hour, fits inside a single-car garage, and drives at highway speeds. With the new prototype, Terrafugia believes that users can learn to operate the TF-X in just five hours. Users will have to learn how to interface with the vehicle; how to determine if it's safe to take off and land; and when to activate the vehicle's parachute system in the event of an emergency.

Switchable Material Absorbs and Stores Sun's Energy

A team at MIT and Harvard University has created a material that absorbs the sun’s heat and stores that energy in chemical form, ready to be released again on demand.The technology provides an opportunity for the expansion of solar power into new realms, specifically applications where heat is the desired output.“It could change the game, since it makes the sun’s energy, in the form of heat, storable and distributable,” says Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT.SourceAlso: See other Materials tech briefs.

Coming Soon - Heat Transfer Simulation in Materials Processing

Engineers in the aerospace, defense, heavy manufacturing, automotive, and medical product industries develop processes to produce materials with specific mechanical and physical properties. In this webinar, we will demonstrate the analysis of conjugate heat transfer problems in COMSOL Multiphysics that are relevant to material processing, and investigate the effects of fluid flow on the quenching of hot components. The analyses show the effects of conduction, convection and radiation for sufficiently high processing temperatures. The webinar will conclude with a Q&A session.

In The Near Future, Will 3D Printers Be Used To Create Human Organs?

3D printers, an emerging technology, use computer-created digital models to produce a variety of objects, including toys, mechanical components, and even food. There is hope now, too, that 3D printers could someday create much-needed organs for transplants. Printing human organs is still years away, but many medical professionals are optimistic and see great promise with the technology. A major challenge will be the ability to create the material, which is biological in nature.
