Crackling noise, which occurs in a wide range of situations, is characterized by discrete events of various sizes, often correlated in the form of avalanches. We report experimental evidence that the mechanical response of a knitted fabric displays such broadly distributed events both in the force signal and in the deformation field, with statistics analogous to that of earthquakes or soft amorphous materials. A knit consists of a regular network of frictional contacts, linked by the elasticity… Expand
Experimental Study on Bi-Axial Mechanical Properties of Warp-knitted Meshes with and without Initial Notches
The results showed that the biaxial tensile behavior of warp-knitted meshes tended to be more isotropic than the other meshes, and the anisotropy level of the diamond warp-Knitted mesh was the lowest, while the rectangular one was the highest. Expand
Mechanical properties of warp-knitted metal mesh fabric under biaxial tension loading
In this study, warp-knitted metal mesh fabric was used as the research object, and its mechanical loading behavior under uniaxial and biaxial stress loading states was studied. The relationship andExpand
Soft matter in confinement and at interfaces
HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching andExpand
Mean-field theories for depinning and their experimental signatures.
This work model forces as an Ornstein-Uhlenbeck process, and solves the model largely analytically, allowing it to describe in all regimes the distributions of velocity, avalanche size, and duration. Expand


Geometry and elasticity of a knitted fabric
This study derives a first-principle mechanical model for the displacement field based on the yarn bending energy, the conservation of its total length and the topological constraints on the constitutive stitches, paving the way to thread-based smart materials. Expand
Emergence of cooperativity in plasticity of soft glassy materials.
An experiment where the emergence of a self-organized plastic flow is observed well before the failure, and the presence of plastic events and the mesostructure of the plastic flow are compared to numerical simulations. Expand
Quasi-periodic events in crystal plasticity and the self-organized avalanche oscillator
An experimental investigation of slowly compressed nickel microcrystals, covering three orders of magnitude in nominal strain rate, is reported, in which unconventional quasi-periodic avalanche bursts and higher critical exponents are observed as the strain rate is decreased. Expand
Crackling dynamics in material failure as the signature of a self-organized dynamic phase transition.
In this description, the quasistatic failure of heterogeneous media appears as a self-organized critical phase transition that exhibits universal and to some extent predictable scaling laws, analogous to that of other systems such as, for example, magnetization noise in ferromagnets. Expand
Soft modes and strain redistribution in continuous models of amorphous plasticity: the Eshelby paradigm, and beyond?
A continuous family of elastic propagators is unveiled, which are identical for the soft modes and for the equilibrium configurations, and interpolates between the standard quadrupolar propagator and the fracture-like one as the anisotropy of the elastic medium is increased. Expand
A simple analytic theory for the statistics of avalanches in sheared granular materials
An analytic model now provides quantitative predictions for the effect of void fractions within a granular medium on avalanche statistics. It will help us understand the dynamics of earthquakes asExpand
On the relevance of disorder in athermal amorphous materials under shear
It is concluded that the statistical mechanisms at play in the emergence of a macroscopic yield stress, and a complex stationary dynamics at low shear rate, are different in thermal and athermal amorphous systems. Expand
Granular Controls on Periodicity of Stick-Slip Events: Kinematics and Force-Chains in an Experimental Fault
It is a long-standing question whether granular fault material such as gouge plays a major role in controlling fault dynamics such as seismicity and slip-periodicity. In both natural and experimentalExpand
Scaling description of the yielding transition in soft amorphous solids at zero temperature
A scaling description of the yielding transition in amorphous solids made of soft particles at zero temperature is proposed that relates the flow curve, the statistics of the avalanches of plasticity observed at threshold, and the density of local zones that are about to yield. Expand
Universality of slip avalanches in flowing granular matter
This work identifies consistent power-law relations truncated by systematic pressure-dependent cutoff, in agreement with recent mean-field theory of slip avalanches in elasto-plastic materials, revealing the existence of a mechanical critical point. Expand
