Congratulations to Jiho on his contact measurements to provide some baselines of properties of PDMS to help with Professor Hutchens’ work on soft fracture using cavitation rheology! And if you are new to the word, just imagine inserting a needle into your jello and blowing a hole in it! This paper can help predict the […]
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 […]
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 presented Erik’s work “Slip versus Flow: Driving Hydrogel Lubricity against an Impermeable Probe” as a poster at the 2016 Soft Matter Symposium at the University of Florida. A great meeting for anyone in soft matter!
How are slip interfaces like fluids? Well in their stress hysteresis under shear, of course. Read more at the Royal Society.
Prof. Dunn will present recent work entitled “Bio-incompatibility? Stability of Hydrogel Layer Lubrication” at the 16th International Conference on Deformation, Yield, and Fracture of Polymers, March 29th to April 2nd 2015. DYFP 2015 Erik Reale, Jiho Kim, and Enrique Chavez Villalobos all contributed to this work.
