Polymer Viscoelasticity in Shear

Polymer materials may exhibit significant viscoelastic behaviour under various type of deformations. A model that can describe various viscous behaviours in simple tension was proposed in a previous work of the laboratory of biomechanical orthopedics. This ...

Rheophysics of concentrated particle suspensions in a Couette cell using a refractive index matching technique

Sébastien Wiederseiner

The main objective of this work is to gain insight into the rheometry and rheology of concentrated non-colloidal particle suspensions. Among the many questions that have as yet received little answers, we are especially interested in the rheometric problem ...

Reduced formulation of a steady fluid-structure interaction problem with parametric coupling

Gianluigi Rozza, Toni Mikael Lassila

We propose a two-fold approach to model reduction of fluid-structure interaction. The state equations for the fluid are solved with reduced basis methods. These are model reduction methods for parametric partial differential equations using well-chosen sna ...

Analysis And Optimization Of Robin-Robin Partitioned Procedures In Fluid-Structure Interaction Problems

Fabio Nobile, Christian Vergara

In the solution of fluid-structure interaction (FSI) problems, partitioned procedures are modular algorithms that involve separate fluid and structure solvers that interact in an iterative framework through the exchange of suitable transmission conditions ...

Efficient Solution of Fluid-Structure Interaction Problems in Computational Hemodynamics

Alfio Quarteroni, Simone Deparis, Paolo Crosetto

Cardiovascular diseases are the first cause of death in industrialized countries. It is now widely established that blood fluid dynamics and its interaction with the vascular wall play an essential role in the development and evolution of vascular patholog ...

Experimental investigation of the spreading of viscoplastic fluids on inclined planes

Christophe Ancey, Steve Cochard

We report experimental results related to the dam-break problem for viscoplastic fluids. Using image processing techniques, we were able to accurately reconstruct the free-surface evolution of fixed volumes of fluid suddenly released a plane. We used Carbo ...

Anisotropic propagation and confinement of high frequency phonons in nanocomposites

Akihiro Sato

We show that self-ordered anodic aluminum oxide containing hexagonal arrays of cylindrical nanopores with submicron periodicity is a versatile model system for the exploration of rich phononic phenomena at gigahertz frequencies, which are intimately linked ...

Adsorption of superplasticizer admixtures on alkali-activated slag pastes

Paul Bowen, Yves Houst

Alkali-activatedslag(AAS) binders are obtained by a manufacturing process less energy-intensive than ordinary Portland cement (OPC) and involves lower greenhouse gasses emission. These alkaline cements allow the production of high mechanical strength and d ...

UHPFRC tensile creep at early age

Eugen Brühwiler, Emmanuel Denarié, Hamid Sadouki, Aicha Kamen

Ultra high performance fibre reinforced concrete (UHPFRC) early age viscoelastic behaviour under tension was investigated. The tests results showed a high creep potential due to the high volume paste (88%). This result is of major importance because the vi ...

Biomechanical forces promote embryonic haematopoiesis

Olaia Maria Naveiras Torres-Quiroga

Biomechanical forces are emerging as critical regulators of embryogenesis, particularly in the developing cardiovascular system. After initiation of the heartbeat in vertebrates, cells lining the ventral aspect of the dorsal aorta, the placental vessels, a ...
