Flow and fracture near the sol-gel transition of silica nanoparticle suspensions
Gustavo E. Gimenes, Elisabeth Bouchaud
We analyze the evolution of the mechanical response of a colloidal suspension to an external tensile stress, from fracture to flow, as a function of the distance from the sol-gel t…
Roughness of oxide glass subcritical fracture surfaces
Gael Pallares, Frederic Lechenault, Matthieu George +4
An original setup combining a very stable loading stage, an atomic force microscope and an environmental chamber, allows to obtain very stable sub-critical fracture propagation in…
Mode I fracture of a biopolymer gel: rate-dependent dissipation and large deformations disentangled
Maxime Lefranc, Elisabeth Bouchaud
We have designed a new experimental setup able to investigate fracture of soft materials at small scales. At high crack velocity, where energy is mostly dissipated through viscoela…
Digital instability of a confined elastic meniscus
John S. Biggins, Baudouin Saintyves, Zhiyan Wei +2
Thin soft elastic layers serving as joints between relatively rigid bodies may function as sealants, thermal, electrical, or mechanical insulators, bearings, or adhesives. When suc…
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…
Bulk elastic fingering instability in Hele-Shaw cells
Baudouin Saintyves, Olivier Dauchot, Elisabeth Bouchaud
We demonstrate experimentally the existence of a purely elastic fingering instability which arises when air penetrates into an elastomer confined in a Hele-Shaw cell. Fingers appea…
