An elasto-visco-plastic model for immortal foams or emulsions [PDF]
, 2007 A variety of complex fluids consist in soft, round objects (foams, emulsions, assemblies of copolymer micelles or of multilamellar vesicles -- also known as onions). Their dense packing induces a slight deviation from their prefered circular or spherical

"Application of carbon black modified cis-1,4-polybutadiene rubber
Hecheng xiangjiao gongye, 2022 The effects of common cis-1,4-polybutadiene rubber （BR）, BR prepared from neodymium catalyst system and carbon black modified BR on sidewall compound properties were investigated by adding different BR to sidewall compound of passenger car radial tire ...

The breakdown of Darcy's law in a soft porous material [PDF]
, 2019 We perform direct numerical simulations of the flow through a model of a deformable porous medium. Our model is a two-dimensional hexagonal lattice, with defects, of soft elastic cylindrical pillars, with elastic shear modulus $G$, immersed in a liquid ...

Variational approach for the flow of Ree-Eyring and Casson fluids in pipes [PDF]
, 2015 The flow of Ree-Eyring and Casson non-Newtonian fluids is investigated using a variational principle to optimize the total stress. The variationally-obtained solutions are compared to the analytical solutions derived from the Weissenberg-Rabinowitsch ...

Non-linear oscillatory rheological properties of a generic continuum foam model: comparison with experiments and shear-banding predictions [PDF]
, 2012 The occurence of shear bands in a complex fluid is generally understood as resulting from a structural evolution of the material under shear, which leads (from a theoretical perspective) to a non-monotonic stationnary flow curve related to the ...

Evaluation of the Mooney Viscosity of Natural Rubber by Near‐Infrared Spectroscopy [PDF]
Spectroscopy Letters, 2005 Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity. NIR reflectance spectra were obtained for a total of 100 samples whose Mooney viscosity (VM in the range 68–95 units) have been determined by the standard reference procedure ...

Structure and properties of high-content rubberized asphalt
Hecheng xiangjiao gongye, 2022 The content of ground tire rubber was limited by its multiple cross-linking networks. High-content ground tire rubber modified asphalt （mass fraction of ground tire rubber more than 30%） binder could be produced by addition of degraded tire rubbers （DR）,

Using the stress function in the flow of generalized Newtonian fluids through pipes and slits
, 2015 We use a generic and general numerical method to obtain solutions for the flow of generalized Newtonian fluids through circular pipes and plane slits. The method, which is simple and robust can produce highly accurate solutions which virtually match any ...
