Liquid jet eruption from hollow relaxation
Élisabeth Ghabache, Thomas Séon, Arnaud Antkowiak
A cavity hollowed out on a free liquid surface is relaxing, forming an intense liquid jet. Using a model experiment where a short air pulse sculpts an initial large crater, we depi…
Wave mitigation in ordered networks of granular chains
Andrea Leonard, Laurent Ponson, Chiara Daraio
We study the propagation of stress waves through ordered 2D networks of granular chains. The quasi-particle continuum theory employed captures the acoustic pulse splitting, bending…
Effect of disorder geometry on the critical force in disordered elastic systems
Vincent Démery, Vivien Lecomte, Alberto Rosso
We address the effect of disorder geometry on the critical force in disordered elastic systems. We focus on the model system of a long-range elastic line driven in a random landsca…
Morphogenesis and propagation of complex cracks induced by thermal shocks
Blaise Bourdin, Jean-Jacques Marigo, Corrado Maurini +1
We study the genesis and the selective propagation of complex crack networks induced by thermal shock or drying of brittle materials. We use a quasi-static gradient damage model to…
Why does a beer bottle foam up after a sudden impact on its mouth?
Javier Rodríguez-Rodríguez, Almudena Casado, Daniel Fuster
A sudden vertical impact on the mouth of a beer bottle generates a compression wave that propagates through the glass towards the bottom. When this wave reaches the base of the bot…
Quantification of errors in large-eddy simulations of a spatially-evolving mixing layer
Marcello Meldi, Maria Vittoria Salvetti, Pierre Sagaut
A stochastic approach based on generalized Polynomial Chaos (gPC) is used to quantify the error in Large-Eddy Simulation (LES) of a spatially-evolving mixing layer flow and its sen…
A stochastic view of isotropic turbulence decay
Marcello Meldi, Pierre Sagaut, Didier Lucor
A stochastic EDQNM approach is used to investigate self-similar decaying isotropic turbulence at high Reynolds number (). The realistic energy spectrum func…
Soft beams: when capillarity induces axial compression
Sébastien Neukirch, Arnaud Antkowiak, Jean-Jacques Marigo
We study the interaction of an elastic beam with a liquid drop in the case where bending and extensional effects are both present. We use a variational approach to derive equilibri…
Nonlocal constitutive laws generated by matrix functions: Lattice Dynamics Models and their Continuum Limits
Thomas Michelitsch, Bernard Collet, Xingjun Wang
We analyze one-dimensional discrete and quasi-continuous linear chains of equidistant and identical mass points with periodic boundary conditions and generalized nonlocal in…
Excitation of fountain and entrainment instabilities at the interface between two viscous fluids using a beam of laser light
Hamza Chraibi, Julien Petit, Régis Wunenburger +1
We report on two instabilities called viscous fountain and viscous entrainment triggered at the interface between two liquids by the action of bulk flows driven by a laser beam. Th…
Transition from wave turbulence to dynamical crumpling in vibrated elastic plates
Benjamin Miquel, Alexandros Alexakis, Christophe Josserand +1
We study the dynamical regime of wave turbulence of a vibrated thin elastic plate based on experimental and numerical observations. We focus our study to the strongly non linear re…
Correlating toughness and roughness in ductile fracture
Laurent Ponson, Ankit Srivastava, Shmulik Osovski +3
Three dimensional calculations of ductile crack growth under mode I plane strain, small scale yielding conditions are carried out using an elastic-viscoplastic constitutive relatio…
Elastocapillary Snapping: Capillarity Induces Snap-Through Instabilities in Small Elastic Beams
Aurélie Fargette, Sébastien Neukirch, Arnaud Antkowiak
We report on the capillary-induced snapping of elastic beams. We show that a millimeter-sized water drop gently deposited on a thin buckled polymer strip may trigger an elastocapil…
Continuum simulation of the discharge of the granular silo: a validation test for the mu(I)-visco-plastic flow law
L. Staron, P. -Y. Lagrée, S. Popinet
Using both a continuum Navier-Stokes solver, with the mu(I)-flow-law implemented to model the viscous behavior, and the discrete Contact Dynamics algorithm, the discharge of granul…
A non-linear rod model for folded elastic strips
Marcelo A. Dias, Basile Audoly
We consider the equilibrium shapes of a thin, annular strip cut out in an elastic sheet. When a central fold is formed by creasing beyond the elastic limit, the strip has been obse…
Shear instability in skin tissue
Pasquale Ciarletta, Michel Destrade, Artur L. Gower
We propose two toy-models to describe, predict, and interpret the wrinkles appearing on the surface of skin when it is sheared. With the first model, we account for the lines of gr…
Front speed in reactive compressible stirred media
Federico Bianco, Sergio Chibbaro, Davide Vergni +1
We investigated a nonlinear advection-diffusion-reaction equation for a passive scalar field. The purpose is to understand how the compressibility can affect the front dynamics and…
Nonlinear transverse waves in deformed dispersive solids
Michel Destrade, Giuseppe Saccomandi
We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) p…
Bending instabilities of soft tissues
Michel Destrade, Aisling Ni Annaidh, Ciprian Coman
Rubber components and soft tissues are often subjected to large bending deformations "in service". The circumferential line elements on the inner face of a bent block can contract…
Characterising the Anisotropic Mechanical Properties of Excised Human Skin
Aisling Ni Annaidh, Karine Bruyere, Michel Destrade +2
The mechanical properties of skin are important for a number of applications including surgery, dermatology, impact biomechanics and forensic science. In this study we have investi…
Nonlinear Correction to the Euler Buckling Formula for Compressed Cylinders with Guided-Guided End Conditions
Riccardo De Pascalis, Michel Destrade, Alain Goriely
Euler's celebrated buckling formula gives the critical load for the buckling of a slender cylindrical column with radius and length as \[ N / (π^3 B^2) = (E/4)(B/L)^2,…
Diffusion of a particle quadratically coupled to a thermally fluctuating field
Vincent Démery
We study the diffusion of a Brownian particle quadratically coupled to a thermally fluctuating field. In the weak coupling limit, a path-integral formulation allows to compute the…
The bending of an elastic beam by a liquid drop: A variational approach
Sebastien Neukirch, Arnaud Antkowiak, Jean-Jacques Marigo
We study the interaction of a liquid drop with an elastic beam in the case where bending effects dominate. We use a variational approach to derive equilibrium equations for the sys…
Elasto-capillary meniscus: Pulling out a soft strip sticking to a liquid surface
Marco Rivetti, Arnaud Antkowiak
A liquid surface touching a solid usually deforms in a near-wall meniscus region. In this work, we replace part of the free surface with a soft polymer and examine the shape of thi…
