New paper: Latching of the click beetle (Coleoptera: Elateridae) thoracic hinge enabled by the morphology and mechanics of conformal structures

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 […]

First visit to “MidMechMat”: a Midwestern workshop on mechanics

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 […]

New paper from Jiho: strengthening the complex fluid analogy

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.
