Inertia-Dilatancy Interplay Governs Shear-Thickening Drop Impact
Anahita Mobaseri, Leonardo Gordillo, Charles Burton +5
Combining high-speed photography with direct force measurements, we investigate the impact dynamics of drops of cornstarch-water mixtures -- a premier example of shear-thickening f…
Photo-Switchable Cross-Linking in Polymer Gels: Effects on Surface Creasing and Network Relaxation during Swelling
Alyssa VanZanten, Surbhi Punhani-Schillinger, M. Reed Blocksome +5
Polymer gels with photo-responsive cross-links enable tunable mechanics and surface morphologies, making them promising for adaptive materials. While prior work on coumarin cross-l…
Emergent clusters in strongly confined systems
Pamud Akalanka Bethmage, Ryker Fish, Brennan Sprinkle +1
Driven suspensions, where energy is input at a particle scale, are a framework for understanding general principles of out-of-equilibrium organization. A large number of simple int…
Rocking, Rolling, and Hopping: Exploring the Multi-motion Capabilities of Rigid and Soft Ellipsoidal Actuators
Shih-Yuan Chen, Michelle M. Driscoll
The problem of a rigid disk rolling down a ramp is a classic problem given to students in introductory mechanics courses. In contrast, systematic studies on the rolling behavior of…
