soft condensed matter, which encompasses a broad range of materials from colloidal …

Cohesive failure of thin layers of soft model adhesives under tension

D Derks, A Lindner, C Creton, D Bonn - Journal of applied physics, 2003‏ - pubs.aip.org
The cohesive failure of soft adhesives is studied using a yield stress fluid as a model
adhesive, which allow to relate the viscoelastic properties of the fluid directly to its adhesive …

Rheophysics of dense granular materials: Discrete simulation of plane shear flows

F Da Cruz, S Emam, M Prochnow, JN Roux… - Physical Review E …, 2005‏ - APS
We study the plane shear flow of a dense assembly of dissipative disks using discrete
simulation and prescribing the pressure and the shear rate. Those shear states are steady …

Yield stress and thixotropy: on the difficulty of measuring yield stresses in practice

PCF Møller, J Mewis, D Bonn - Soft matter, 2006‏ - pubs.rsc.org
The yield stress of many yield stress fluids has turned out to be difficult to determine
experimentally. This has led to various discussions in the literature about those experimental …

Avalanche behavior in yield stress fluids

P Coussot, QD Nguyen, HT Huynh, D Bonn - Physical review letters, 2002‏ - APS
We show that, above a critical stress, typical yield stress fluids (gels and clay suspensions)
and soft glassy materials (colloidal glasses) start flowing abruptly and subsequently …

Microscopic mechanism for shear thickening of non-Brownian suspensions

N Fernandez, R Mani, D Rinaldi, D Kadau, M Mosquet… - Physical review …, 2013‏ - APS
We propose a simple model, supported by contact-dynamics simulations as well as rheology
and friction measurements, that links the transition from continuous to discontinuous shear …

Cellulose ethers influence on water retention and consistency in cement-based mortars

L Patural, P Marchal, A Govin, P Grosseau… - Cement and Concrete …, 2011‏ - Elsevier
Cellulose ethers (CE) are commonly used as additives to improve the quality of cement-

Results of numerical flow simulations for two slump geometries, the ASTM Abrams cone and
a paste cone, are presented. These results are compared to experimental results in the case …

A physical model for the prediction of lateral stress exerted by self-compacting concrete on formwork

G Ovarlez, N Roussel - Materials and Structures, 2006‏ - Springer
In this paper, a model is proposed to describe the evolutions of the lateral stress exerted by
self compacting concrete (SCC) on a formwork during and after casting. The predictions of …
