When you see these images of the beetle peg morphology, doesn’t it make you wonder about the contact mechanics? Us too! In this work by Ophelia and Lihua, we describe how the snap of the click beetle is enabled by the rigid peg. But we also say that the contact mechanics matter. So interesting how […]
Preparing for a life in academia has many aspects, none of which a single mentor can adequately cover! Illinois offers 30 students throughout the Grainger College of Engineering a fellowship and two semesters of workshops and assignments to cover more of the bases; it’s the Mavis Future Faculty Fellows Academy. I’m ecstatic to report that […]
My collaborators Aimy and her student Ophelia presented two great talks about our ongoing work understanding how energy is generated and leveraged in the snap maneuvers of click beetles! Check out our prior paper for more details, and be on the lookout for at least 2 more publications this year! Many thanks to Sheila Patek […]
All PhD students in the lab had big leaps forward this semester.
Thank you to the faculty committee for their excellent feedback and guidance on Jiho’s presentation: “Lubrication mechanics in loosened polymer networks of polyacrylamide surfaces.”
Two weeks ago Jiho had the opportunity to participate in ‘Paper2Tree’ in which the lab supports the planting of a tree in the community to give back after publishing a journal articles. Following Jiho’s paper modeling duration-dependent lubrication earlier this year, he selected a Shingle Oak to be planted in King Park, and also led […]
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.
