Professor Dunn, Lihua, and visiting scholar Chao had a great time in downtown Chicago for the Tribology Frontiers Conference organized by Dr. David Burris from the University of Delaware. Professor Dunn presented Prabhakaran & Hao’s work on wear of hardened steels — take a journey under a train to get a feel for it. Lihua […]
Thanks for the opportunity to come by! You can listen here on SoundCloud to learn about how surfaces play an important role in design of materials, and why it’s important for the biomedical implants of the future!
Shab, Jiho, and Professor Dunn went up to Illinois Institute of Technology (Chicago) last week to present posters at the 4th annual workshop on Mechanics of Materials and Structures. The keynote speakers were excellent, Michael Ortiz from CalTech and Heinrich Jaeger from the University of Chicago, and we met many talented researchers working in all […]
How does a high-water-content hydrogel surface respond to step changes in speed? Jiho measured the lubrication mechanics of a complex shear interface through tribo-rheometry to try and figure it out. Out of all the possible responses, we find a combined time-dependent and shear-thinning response, just like a complex fluid. Check it out for more details.
Prof. Dunn worked with high school girls attending the Girls Building Awesome Machines (GBAM) camp here at Illinois last week to define tribo-corrosive wear using a system we can all enjoy: the Tootsie Pop! The last line of the classic commercial says that the world may never know “how many licks” it takes to get […]
We had a great time at STLE 2018 in Minneapolis. Both Shab and Jiho presented their work in the “Materials Tribology” track, and Chris, Prabhakaran, and Hao presented posters. Congrats to Chris on his poster award! Below you can see some of the nice contact area measurements he has been making over the past few […]
All the graduate students took turns describing to groups of high school students how a record player works. Then the students were challenged to listen to a song from the Guardians of the Galaxy soundtrack and match up sound signatures with micrographs of the grooves on the record surface. A groovy time was had! A […]
We are happy to be a part of this joint center, with an exciting project building a dual-disk wear tester and studying the origins of steel wear in combined rolling/sliding conditions.
We’ve upgraded so many capabilities: stylus profilometer, in situ confocal microtribometer, thrust washer tribometer, and the list goes on! It’s been a good building year. Come see us in MEL later this year.
Leading tribologists in the Midwest met at Argonne to coordinate efforts.
