Bridging the Gap Between Avalanche Relaxation and Yielding Rheology Open
The yielding transition in amorphous materials, whether driven passively (simple shear) or actively, remains a fundamental open question in soft matter physics. While avalanche statistics at the critical point have been extensively studied…

Elasticity and rheology of auxetic granular metamaterials Open
The flowing, jamming, and avalanche behavior of granular materials is satisfyingly universal and vexingly hard to tune: A granular flow is typically intermittent and will irremediably jam if too confined. Here, we show that granular metama…

Self-Aligning Polar Active Matter Open
Self-alignment describes the property of a polar active unit to align or anti-align its orientation towards its velocity. In contrast to mutual alignment, where the headings of multiple active units tend to directly align to each other -- …

Elasticity of self-organized frustrated disordered spring networks Open
There have been some interesting recent advances in understanding the notion of mechanical disorder in structural glasses and the statistical mechanics of these systems' low-energy excitations. Here we contribute to these advances by study…

Active Solids Model: Rigid Body Motion and Shape-changing Mechanisms Open
Active solids such as cell collectives, colloidal clusters, and active metamaterials exhibit diverse collective phenomena, ranging from rigid body motion to shape-changing mechanisms. The nonlinear dynamics of such active materials remains…

Path integral description and direct interaction approximation for elastic plate turbulence Open
In this work, we apply the Martin-Siggia-Rose path integral formalism to the equations of a thin elastic plate. Using a diagrammatic technique, we obtain the direct interaction approximation (DIA) equations to describe the evolutions of th…

Auxetic behavior on demand: a three steps recipe for new designs Open
Despite their outstanding mechanical properties, with many industrial applications, a rational and systematic design of new and controlled auxetic materials remains poorly developed. Here a unified framework is established to describe bidi…

Critical yielding rheology: from externally deformed glasses to active systems Open
The Herschel–Bulkley law observed in active systems presents a clear difference in critical exponents compared to shear dynamics. It suggests the existence of different universality classes in yielding transition under different driving co…

Elastic weak turbulence: From the vibrating plate to the drum Open
Weak wave turbulence has been observed on a thin elastic plates since the work by Düring et al. [Phys. Rev. Lett. 97, 025503 (2006)PRLTAO0031-900710.1103/PhysRevLett.97.025503]. Here we report theoretical, experimental, and numerical studi…

Micromechanical theory of strain stiffening of biopolymer networks Open
Filamentous biomaterials such as fibrin or collagen networks exhibit an enormous stiffening of their elastic moduli upon large deformations. This pronounced nonlinear behavior stems from a significant separation between the stiffnesses sca…

A Kolmogorov spectrum for strongly vibrating plates Open
In fluid turbulence, energy is transferred from a scale to another by an energy cascade that depends only on the energy dissipation rate. It leads by dimensional arguments to the Kolmogorov 1941 (K41) spectrum. Remarkably the normal modes …

Exact result in strong wave turbulence of thin elastic plates Open
An exact result concerning the energy transfers between nonlinear waves of a thin elastic plate is derived. Following Kolmogorov's original ideas in hydrodynamical turbulence, but applied to the Föppl-von Kármán equation for thin plates, t…
