Excess Floppy Modes and Multi-Branched Mechanisms in Metamaterials with Symmetries
Luuk A. Lubbers, Martin van Hecke
Floppy modes --- deformations that cost zero energy --- are central to the mechanics of a wide class of systems. For disordered systems, such as random networks and particle packin…
Dynamical Theory of the Inverted Cheerios Effect
Anupam Pandey, Stefan Karpitschka, Luuk A. Lubbers +5
Recent experiments have shown that liquid drops on highly deformable substrates exhibit mutual interactions. This is similar to the Cheerios effect, the capillary interaction of so…
Inverted Cheerios effect: Liquid drops attract or repel by elasto-capillarity
S. Karpitschka, A. Pandey, L. A. Lubbers +5
Solid particles floating at a liquid interface exhibit a long-ranged attraction mediated by surface tension. In the absence of bulk elasticity, this is the dominant lateral interac…
Discontinuous Buckling of Wide Beams and Metabeams
Corentin Coulais, Johannes T. B. Overvelde, Luuk A. Lubbers +2
We uncover how nonlinearities dramatically alter the buckling of elastic beams. First, we show experimentally that sufficiently wide ordinary elastic beams and specifically designe…
Drops on soft solids: Free energy and double transition of contact angles
Luuk A. Lubbers, Joost H. Weijs, Lorenzo Botto +3
The equilibrium shape of liquid drops on elastic substrates is determined by minimising elastic and capillary free energies, focusing on thick incompressible substrates. The proble…
Dense Suspension Splat: Monolayer Spreading and Hole Formation After Impact
Luuk A. Lubbers, Qin Xu, Sam Wilken +2
We use experiments and minimal numerical models to investigate the rapidly expanding monolayer formed by the impact of a dense suspension drop against a smooth solid surface. The e…
Symmetric and Asymmetric Coalescence of Drops on a Substrate
J. F. Hernandez-Sanchez, L. A. Lubbers, A. Eddi +1
The coalescence of viscous drops on a substrate is studied experimentally and theoretically. We consider cases where the drops can have different contact angles, leading to a very…
