A minimal-length approach unifies rigidity in under-constrained materials
Matthias Merkel, Karsten Baumgarten, Brian P. Tighe +1
We present a novel approach to understand geometric-incompatibility-induced rigidity in under-constrained materials, including sub-isostatic 2D spring networks and 2D and 3D vertex…
Normal stresses, contraction, and stiffening in sheared elastic networks
Karsten Baumgarten, Brian P. Tighe
When elastic solids are sheared, a nonlinear effect named after Poynting gives rise to normal stresses or changes in volume. We provide a novel relation between the Poynting effect…
Viscous forces and bulk viscoelasticity near jamming
Karsten Baumgarten, Brian P. Tighe
When weakly jammed packings of soft, viscous, non-Brownian spheres are probed mechanically, they respond with a complex admixture of elastic and viscous effects. While many of thes…
Coarsening and mechanics in the bubble model for wet foams
Kseniia Khakalo, Karsten Baumgarten, Brian P. Tighe +1
Aqueous foams are an important model system that displays coarsening dynamics. Coarsening in dispersions and foams is well understood in the dilute and dry limits, where the gas fr…
Nonlocal elasticity near jamming
Karsten Baumgarten, Daniel Vagberg, Brian P. Tighe
We demonstrate that the elasticity of jammed solids is nonlocal. By forcing frictionless soft sphere packings at varying wavelength, we directly access their transverse and longitu…
